Hello ACME!

The Call for Adoption
for draft-wendt-acme-authority-token-jwtclaimcon closed on 2025-09-22.
Despite MCR's positive review, one comment does not constitute working
group consensus. I am going to leave this document in datatracker in the
state Candidate For Adoption. I encourage the authors to present at the
ACME session it IETF 124 with the goal of drumming up more interest in this
draft, particularly from implementers.
