I wonder if that can be solved by speculative request?

Let the connection initiator say "If you can do x and z, please do
so", and allow the responder to say either "OK, I can do x and z; by
the way the full capabilites I support are w, x, y and z", or
"Sorry, can't do that; I have capabilities w, x, and y".
