I am not sure that we would like to give up that easily the property
that we have now to clean up past temporary files only at postmaster
startup and only when not in recovery. If you implement that, there is
a risk that the backend you are starting is eating the connection slot
and by consequence its temporary schema and its set of temporary tables
on which one may want to look into after a crash.

Yeah. Here we can do something. This does not sound much difficult to
me.
