Roundtrips are important, but I don't think anyone expects
everything to happen in the minimum number of round
trips, in ALL cases. That is, I think we need e.g. shared secret
mechanisms with a small number of roundtrips in EAP, and
we need some mechanisms that have a small number of
roundtrips. But we already have today TLS-based EAP
tunneling schemes, some of which are quite chatty.
So I think it would be fine to have some additional
roundtrips when you using something from another

(Nevertheless, I'm in favor of the bindings approach.)
