I don't ride on wet dirty lanes and I hadn't a single flat over
~8000 km that I did on the road bike that I built in 2023.
Perhaps I'm lucky. However, tubeless tyres with sealant could
also play a role.
I've got quite some flats in the years before. During that time,
I often didn't carry a spare tube, but a repair kit only.
Generally, I prefered those from Rema
<https://rema-tiptop.de/en/products-services/rema-motion/products/tire-repair-material/bicycle/>,
especially this kit: <https://www.bike-discount.de/en/rema-tip-top-repair-kit-tt-04>
Nowadays, I carry a spare ultralight TPU tube and a tubeless
repair kit in my saddle bag, just in case. <https://www.bike-discount.de/en/maxalami-road-tube-tubeless-repair-kit>
I haven't had to use it yet.

I'll see your two flats and raise you one. I got 3 today, and didn't
have a spare. I fixed the first two flats, but when I got to the third,
I called to get a ride home.
I'm due for a new set of tires anyway, and with the frequency of thorns,
I'm inclined to add kevlar inserts.

I stopped at the LBS and got a set of Bontrager tires that are hardened,
but they're very difficult to mount.-a I got one on the rear wheel with a lot of effort, but I'm not yet sure that I don't have the tube pinched
under the bead, and I can't get it to inflate.
I don't think this is the right tire for my Mavic Kysrium rims, and I'm going to go back to the shop and return the tires. I don't know if the lighter Bontrager model would be better, but I think I can do better
with something like Continental Gatorskins.
I've never been excited about Trek and tires. Many years ago, the bike I
was riding had Araya rims, and the nearest shop to me was a Trek shop
that mostly sold Trek's Matrix tires. For some reason, the combination
of Araya and Matrix was not good, and I had a lot of problems with blow- offs when mounting those tires. The blow-offs problem went away when I
moved to some Continental line that was skinwalls, and then further when
I moved to wheels with Mavic rims.
Knowing that Bontrager was a mountain bike brand before Trek acquired
them, I've never been excited about their road stuff. I know that Trek
has had around 30 years of producing stuff, and for what they're doing, "Bontrager" is merely a brand name, which is why I was willing to give
them another try. I have no idea of what Trek might be producing in the
way of high-end performance tires, but for what I need, I think I'm convinced that I can do better with other tire producers.

Kinda depends on wet your area is? Gatorskins while absolutely tough and light, have rock hard compound and thus are rather nervous in the wet,
hence the rCLSkaterskinsrCY name they have acquired if one lives in moist environments. I found the grip worse than even the cheapest of cheap tyres one could find!

In my case, drier than you can possibly imagine. I might see rain once
in a year, but only if I get caught out during a monsoon storm.
Even if both of my tires are several years old, the age is accelerated
by arid conditions. Our primary environmental condition is a kind of
thorn commonly known as "goats heads", small and really nasty. The
pointy part impales itself in something soft (e.g., bike tires, shoe outersoles, and God forbid, soles of feet) and breaks off, leaving a
larger chunk (probably seed to re-germinate). Especially common near
open agricultural space. All of the holes I've patched are pinhole-sized
-- very probably goats heads.
For me, part of the attraction of this tire model is sturdy tread for
thorn resistance, and I don't need a lot in the way of performance, especially cornering. It may be that this tire is tough enough that
it's unlikely that I'll pick up a thorn, but I can't imagine what it
would be like if I ever flatted out on the road, and had to dismount a tire.
The other mistake I made was that this particular shop is part of a
local chain. I mostly like them, although I normally interact with
another location that is more focused on road bikes, and this one is
smaller -- more emphasis on mountain bikes and general-purpose riders. Historically, they've been primarily selling Specialized, but a couple
of years ago, they told me that they had a hard time getting stock, so
they dumped Specialized and shifted to Trek. And for the shop I went to, they only stock the Bontrager tires.
There's a bigger chain in the area -- they also are primarily Trek, but they're big enough that I think their tire selection isn't Bontrager exclusively. One insider thing I know is that with Continental, shops
that sell their stuff have to commit to a minimum volume of sales, and
as a result, if a shop has Continental, they're going to have more stuff
and better variety of stock.

Perhaps. But two of these in 32-622 / 28x1.25 have a weight of
810 g * 2 == 1.62 kg. Two of my GP 5000 (28-622) weight 265 g *
2 == 0.53 kg.
A kilogram here, a kilogram there ...
I used to ride my old commuter bike from 1995 (a Peugeot PR 3000)
with 25 mm slick tyres. Got it with 23 mm tires. :-)

With the gravel bike at same pressures you could feel the difference, but

I've never had any problems with Bontrager stuff, though I haven't ever
put any of it through any serious paces like racing off-road except for
the Bontrager CX frame I have - of course that was actually built by Bontrager pre-trek so it didn't have any other bontrager stuff on it
when I was racing it.
After I decided to set that up for my wife a few years ago I bought Trek/Bontrager CX wheels and tires in the same black/red color scheme to
get it all matchy-matchy. I've only ridden it once since then but it
rode really smooth and stable. She doesn't take it out much but her only complaint is that she's not a fan of drop-bars.

Yes that's exactly correct.
Reviewing theory, or Michelin's original patent, the tire needs
to drop into the center well of the rim on one side while the
edge is lifted over the top of the rim on the other side.
With a fat classic MTB rim it's effortless.
For many modern 'tubeless compatible' rim sections or for very
narrow rims, the clearances are minimal so by ending at the
valve, tire changing is less daunting. The only place the tire
cannot drop in the rim center is at the valve.

I'll be interested to see what you experience.
I'm finally through my adventures. I returned the Bontragers, although
it was useful that a shop mechanic reminded me that tires do stretch
some after they've been ridden, and over time, they're easier to mount
and dismount.
I went to another shop and paid a little more than I had really intended
for high-end hard-shell Continental Gatorskins. Those were also kind of stiff going on, and then I ended up having problems with the tubes I got
at the Trek shop. One tube seems to have valve problems and isn't
holding pressure, and when mounting the other one in one of the
Gatorskins, I goofed and got the tube caught under the bead and got a blowout when I mounted.
Besides the Trek shop (my regular one is the same chain but a different location, not as close to my house, but more focused on road bikes),
there is also a Specialized shop nearby. They're small enough (and
almost exclusively Specialized) that I don't go to them regularly, but
the people who run the shop are serious riders, and not prone to hiring sales-droids. Thus, I got a couple of Specialized tubes, and got
everything mounted correctly -- finally. I got a ride in this morning,
and glad of it, but still feeling the effects of my long layoff. After a
few hundred miles, I'm definitely more comfortable -- longer distances, faster speeds, and where I'm now getting out 3 days a week, and
beginning to get consecutive days, but today wasn't super-satisfying. If
I ride tomorrow, it will probably be relatively short before going
longer on Saturday.
