Heating of a connector happens because of resistance. The same resistance
will result in more heat with more current.

The contact spring tension has to be a compremise between
insertion force versus contact force so why can't someone
devise a switched 13A socket which uses a cam arrangement to
increase the contact force, reducing resistance, when the
switch is moved to the on position?

(Personally, I prefer unswitched sockets but even when you
find them these days, they are more expensive than the
switched version!)
