Well just on general principles, if standards are good then
we ought to have as many as possible, right?

have used clippless Pedals in the past, I didnrCOt use the SPD-SL aka road design that the SLR is replacing?
I always used SPD which worked well enough and one can walk around in them, apparently the SLR is easier to walk in and clip into, that would be side bonus as some roadies seem to have real trouble doing so in a timely
manner! Sunday club riders are one thing but I do pull past commuters as
well if they want to play with the lime bikes thatrCOs their choice but I prefer to clear ahead of the junction away from the throng.

Two entirely different things.
Road shoes are necessarily rigid, usually carbon now but not very
different overall from steel-shank cycling shoes 120 years ago.
Successful road cleat designs allow fast engagement/release while secure when pulling up on the pedal. The cleats are nearly all broad nylon
plates (original Look, new mini 'keo' look, SPD-SL and others).
Besides the ubiquitous three 5mm hole road cleat mounting pattern,
Look's 1984 design patent specified the sole curvature. Look offered
their licensed design broadly and cheaply.-a Road shoe manufacturers
quickly standardized around it and remain uniformly 'Look compatible'
these many years later.
SPD was expressly designed for offroad, with a much smaller steel cleat
on two 5mm bolts. The design inherently pushes mud and crud out when engaging and allows mounting on a flexible sole with rubber tread surrounding that small steel cleat, again expressly for off pavement use.
Recreational and commuting riders do often use the less expensive SPD
system on Sunday morning club bikes and commuters, where a flexible shoe sole is considered important.-a You won't find road format pedals and
shoes in mud racing!

are mostly carbon fiber for sole. I like the very positive
engagement and locked in ridged platform feeling. In fact
riding a bike with normal without clips is a challenge I
have practice. Given my outdoor riding now on the catrike I
still prefer the road SPD-SL and on a trike you need clipless.
The thought of going to a whole new system is a not
something I really want to do and I assume not compatible
with the old. However, in my case it might not be the worst
case problem given all my 105 pedals on the trainer and
Catrike are very old with well over 20,000 miles on them. I
don't need float either really but mine at the moment are
the 6 degree floaters.
The bike industry wants you buying new things and new
technology all the time. Personally I want to buy components
and bike that work as intended with little maintenance and
adjusting. They don't have to work forever but while working
they work and the lifespan is reasonably known. I also want
components that are not difficult to service or require new
tools with every change.
Therefore, BSA thread BB, exposed cables easy to swap out,
predictable FR and RD that shift precise and can be adjust
easy. I don't need something that is better and great so I
can faster. I am going as fast as my 65 years can generally
manage. I am not getting faster that is for sure. But
complicated replacement of components whatever they be is
not easier either. It is probably good for the mind but
added stress to get it correct I don't need.
Rant over.
