Certainly, documenting it in udp(7) or whatever would be fine too. The
problem though is that someone setting up a NFS mount isn't as likely
to see it there as they would if it were in nfs(5).

I see no harm in documenting it here too. At the very least, if you're
going to put this into udp(7) instead then nfs(5) should refer to that
manpage and chapter explicitly.
