You want to say that if an authzid is set then it's sent in both, a=
and user=.  That's because otherwise you'd not have a mechanism that
could be conceived as a GS2 mechanism or you'd not interop with
Google.

A little duplication will have to be accepted if you want both, a
GS2-interoperable and Google-interoperable mechanism.  It's the
consequence of not having noticed and fixed this at Google long ago.
I think that's fine.
