Hi Nat,

I suppose you saw the FAPI WG ticket to consider adding an AS metadata parameter for the request object endpoint:

https://bitbucket.org/openid/fapi/issues/134/

Perhaps that issue should be addressed here, in the OAuth WG. But I'm not sure what can be done at this stage, with draft-ietf-oauth-jwsreq-15 have gone to the IESG.
