Doing "fstat | egrep 'unix dgram'", I see syslog, plus a bunch of stuff
of my own (most of my code using such sockets uses them to transfer
file descriptors between processes at run time with SCM_RIGHTS, though
there are exceptions).

Whether there is value in forwarding AF_LOCAL sockets is questionable.
Such forwarding will necessarily break certain facilities which some
users of AF_LOCAL assume will work, such as SCM_CREDS, and I don't
think it's unreasonable for code using AF_LOCAL sockets to blindly
assume that both ends are running on the same machine (and thus, for
example, agree on the size and byte order of ints)....
