No objection here. You could also allow "none" (or maybe that falls out
of the list case by writing an empty list), with the understanding that
"none" is a useless setting on Windows or any other platform that
doesn't support Unix sockets.

I think it's the same argument: neither of these variables are likely to
be touched by application code, only by config file entries; so we need
not feel compelled to provide backwards-compatibility options.

Yeah, I don't think that's worth the trouble. It would open up a bunch
of definitional issues (like which port number do we use as the seed for
the shared memory key), without actually buying much useful functionality.
