Transport issues such as base64 vs binary field values are not nearly as interesting as the user experience and abstract protocol.

Are people expecting this to work as a HTTP Authentication Header protocol? As new attributes embedded into an HTML form? Or in some other manner entirely? What is the expected user experience? How does that experience degrade if the user e.g. cancels or taps an authenticator that does not meet server policy?

In all honesty, we would be better off representing the whole response as base64url-encoded CBOR if we were talking about ease-of-transmission to the relying party server. Use of JSON is optional for constructing requests and verifying responses, use of CBOR and COSE and the processing of other binary-structured messages are not.
