Richard Barnes:

The credential request contains a proof of possession of a private key by the client.  The specification has a `proof_type` parameter that allows for multiple proof types, but only `jwt` is actually defined.  Is this flexibility actually needed?  It seems like if a client is already doing the work of integrating with this API, signing a JWT to prove possession is probably not a lot of extra work.
