I think handling ai_family == PF_LOCAL is good.

It seems much less specified than what "hostname", "4711" is.

I think glibc used to do that, which I fail to see the point of. What
would a nodename mean for a PF_LOCAL address? I can see nodename =
NULL, servname = foobar -> "/tmp/foobar". But nodename = "something",
serername = NULL and nodename = servname = NULL seem rather undefined
