Well, yeah:

 1) (New) clients need to implement negotiating Session Establishment to
interact with servers that advertise Session Establishment, but only if
advertized.

 2) Clients may have to negotiate Session Establishment to work around
broken servers that don't advertise, but do require it to be negotiated.
I hope this is never the case, though. If there are such implementations
in the wild, I hope to have them fixed *and* implement this draft.

 3) Clients already supporting Session Establishment, SHOULD (per the
upcoming version of this draft) skip negotiating Session Establishment.
