i didn't claim that all UAs are smart and implement latest specs.  but
in most UAs, even in very old ones, it is possible to manually configure
the reg int.  so if user's UA is behind nat, the user can usually
configure reg int and make it work from behind nat.  on the other hand,
very few old UAs support tcp.
