Yes, I think that's a good idea.

I agree that neither handles it explicitly.  Ray's singular use case
doesn't really need it, and our draft can handle ports through the DNS
address family mechanism if needed, albeit less compactly that could
be otherwise envisioned.  If this were something that others think
should somehow be made explicit via some other mechanism, I could see
incorporating that.
