I had assumed using the request object is mutual exclusive to use of URI query 
parameters. Did I misinterpret the draft?

> Abstract:
>    The authorization request in OAuth 2.0 described in RFC 6749 utilizes
>    query parameter serialization, which means that Authorization Request
>    parameters are encoded in the URI of the request and sent through
>   user agents such as web browsers.  While it is easy to implement, it
>    means that (a) the communication through the user agents are not
>    integrity protected and thus the parameters can be tainted, and (b)
>    the source of the communication is not authenticated.  Because of
>    these weaknesses, several attacks to the protocol have now been put
>    forward.
>   
>    This document introduces the ability to send request parameters in a
>    JSON Web Token (JWT) instead, which allows the request to be signed
>    with JSON Web Signature (JWS) and/or encrypted with JSON Web
>    Encryption (JWE) so that the integrity, source authentication and
>    confidentiality property of the Authorization Request is attained.
>    The request can be sent by value or by reference.
