Is there a clear statement somewhere along the lines of “parameters (other than
“request” or “request_uri”) are only allowed to be in the signed object if a
signed object is used”? That’s the kind of thing I was looking for and didn’t
find.

The intent of the change is to only allow the paramaters to be in the signed
object if a signed object is used.
This requires State, nonce etc to be in the JWT. Only one place to check will
hopefully reduce implimentation errors.
This also allows us to remove the caching text as we now have one JWT per
request, so caching won't happen.

I *believe* the intent is that *all* parameters must be in the request object,
but the spec doesn’t actually say that, as far as I can tell. Or maybe the
intent is that parameters must not be duplicated between the query parameters
and the request object.
One or the other of these statements should be explicitly included in the
specification. Of course, I could have missed the statement I’m asking for in
my review, in which case please let me know what I missed.
Thanks,

Based on feeback from the IESG we have removed some of the optionality in the
draft.
It is a shorter read than draft 12.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Web Authorization Protocol of the IETF.
Title : The OAuth 2.0 Authorization Framework: JWT Secured
Authorization Request (JAR)
Authors : Nat Sakimura
John Bradley
Filename : draft-ietf-oauth-jwsreq-13.txt
Pages : 27
Date : 2017-03-30
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.
