It will be accepted.


What could wind up being a bit more process stuff is that the draft also
concerns JOSE, which now has an active WG (looks like since about 5 days

(more of Document Shepard, WG chairs, Area Directors thing).

Generically, the algorithms can interact badly. However, HPKE will not
interact badly with HPKE.

Downrefs are meant for situations like this. I did author one PS RFC with
downref to CFRG informational RFC, I don't think I was even asked to
justify that.
