I reviewed  draft-ietf-ipsecme-eddsa on behalf of the opsdir during it's IETF
Last call.

This standards track draft introduces an importance change in the IKE
negotiation in that the sender can indicate that it hash algorithms which do
not require prehashing and can instead operate on arbitrary length data.

It also goes on to make a more strong requirement then RFC 8032 (which is
informational) that:

" The pre-hashed versions of Ed25519 and Ed448 (Ed25519ph and Ed448ph
   respectively) MUST NOT be used in IKE."

Changes to IKE negotiation require careful review, but I am satisfied that this
explicit signal improves the handling of support for the edwards curves.
