Assuming CFRG chairs really did declare consensus on Ed448 hash, then the final characteristics of Ed448 are known and I have a reference implementation. And the PKIX draft looks implementable (has wrong example?) More serious interop hazard is what to do with X25519/X448 and THS (some of the proposed stuff is not wire-compatible). -Ilari
