After the program that listened on them exited they are useless and
cannot be reused, they hence *must* be removed before another program
can listen on them again.

Uh? First of all, such an fs does not exist.

Secondly, as mentioned a unix socket is useless in the fs after the
program that listened on it exited, hence automatically deleting the
unix socket as soon as it exited would actually be a good idea.
