Never run a granny charger from an extension lead.

There's no logical reason why not, the problem is that many extension
leads are not engineered to carry 10A or more for hours on end without
getting hot or even catching fire.
Sometimes the plug or socket are poor and get hot
Sometimes the cable is too light a gauge and gets hot
Sometimes the cable is wound onto a drum or otherwise constricted and
gets got and melts.
Before I got my home charger I was using a 13A charger and experimented
with various cables. I ended up making my own with heavy cable and
connectors that were found, by trying several, to run cool. Even that
would get warm if looped on itself or covered.
So the only advice that can be given in general is: don't.
specifications? It is difficult to argue that a plug or socket cannot
carry 10 amps when they were designed for 13 amps in the days of 3 bar
fires.

The 15A plug is alive and well and used with most theatre lamps, at
least in amateur environments.

Because you can't use ring mains without local fusing, at least at the socket, and a fuse in the plug is more versatile. We used to have three
sizes of mains plug, each connected to appropriate fuses in the
fusebox. You still had to be careful not to overload any group of
sockets connected to only one supply cable, and in general houses
contained very few power sockets of any kind. The vacuum cleaner
normally had a bayonet plug, to be used in the nearest light socket.

Typically if you want more than 3kW you go three phase. And I can
see that happening in the future with new builds in the 'executive
homes' class.

I assume because of the same reason every one voted for Brexit - so the
need to be different and make our own minds up, or really cut corners
and penny pinch.
So rather than multiple radial circuits with individual fuses or circuit breakers we have the dreadful ring main which was designed to save
copper. This meant you needed to have fuses in the plugs, and to ensure
you didn't use the existing plugs, they had to come up with a new plug, hence the uk 13amp plug which I assume contains less copper than the
15amp version.

I believe that rings are inherently dangerous. If there is a break in
the ring-a you lose the redundancy. If the break is close to one end of
the ring, you end up with a long radial circuit which is easily
overloaded. You cannot test for breaks without disconnecting something.

Unlike today when... Ah!
Last week they couldn't because all the copper had been nicked.
Apparently the extra-fast charging points, with their lovely thick cables, are particularly attractive to pikeys.
