Hi all,

Those of you who were in the working group meeting today know that we ran out 
of time to discuss 
https://datatracker.ietf.org/doc/draft-ietf-oauth-rfc8725bis/.  The very short 
deck that I would have presented is at 
https://datatracker.ietf.org/meeting/124/materials/slides-124-oauth-json-web-token-best-current-practices-00.
  Per my extemporaneous verbal description of the status today, I believe we've 
described in the draft all the new JWT implementation errors that have come to 
light since RFC 8725 was published in 2020 and mitigations for them.  On that 
basis, I was asking for additional reviews and then potential working group 
last call.

At the end of our time, Brian Campbell called our attention to his comments in 
Madrid about how we've taken on a big job.  These comments are minuted at 
https://datatracker.ietf.org/meeting/123/materials/minutes-123-oauth-202507251230-00.
  Search for "I hope you're prepared for what you're getting into" to find 
them.  From the minutes, it seemed that Brian raised three points:

  1.  Coordinate with 
https://datatracker.ietf.org/doc/draft-ietf-jose-deprecate-none-rsa15/
  2.  Coordinate with 
https://datatracker.ietf.org/doc/draft-ietf-jose-hpke-encrypt/
  3.  The current RFC 8725 on "zip" is causing interoperability problems

I understand the intent of the first two, but I'll point out that neither of 
these drafts have gone through a successful working group last call.  There's 
precedent in OAuth for not holding up publishing a BCP because other 
developments may update the BCP later.  In particular, we decided not to hold 
the OAuth Security BCP [RFC 9700] until we'd addressed already known 
vulnerabilities, including the one being addressed in rfc7523bis.  Our logic 
was that it is better to publish the BCP in a timely fashion to get a set of 
useful information out to people and that the BCP will be updated when the 
mitigations for additional vulnerabilities are settled.  As an individual I'll 
say that I think that precedent should also apply here.

As for "zip", I would invite an issue at 
https://github.com/oauth-wg/draft-ietf-oauth-rfc8725bis or on the mailing list 
with a specific text change proposal.  Then the working group can consider it.

Thanks to those who agreed to review the draft!

                                                                Best wishes,
                                                                -- Mike
