There might be reason to resurface this discussion but the use of OKP was
definitely not the “clear winner” at and around the last meeting. There was not
consensus to switch away from AKP in the first place, and the poll that was
run on whether to use OKP had a very clear outcome: "Poll - Should OKP be
used for PQC KEM Keys: Yes 0 / No 5/ No Opinion 7" from
https://datatracker.ietf.org/doc/minutes-123-jose-202507241500/.
The draft-ietf-jose-pqc-kem published should reflect that outcome as the
baseline before any consensus call is made.
