Not yet perhaps. I figure there's value in some more crypto clue
validating that the text of the drafts looks fine since they're
not simple transcriptions and e.g. maybe some more test vectors
or something might be suggested and added. At that point shooting
these via the independent submission stream is the usual thing
and after that it'd be time to head to TLS or IPSECME.

Right. Those are the things it'd be great to have seen
informed comment on here.
