Actually there is currently only one draft, draft-shin-augmented-pake,
which follows my negotiation process. The
draft-harkins-ipsecme-spsk-auth author did say he is going to change
his draft, but the draft is not yet there, and then there is
draft-kuegler-ipsecme-pace-ikev2 (which you are co-author) which is
doing negotiation differently and I do not know whether that is going
to change to use same way than others.

As an IANA Expert for the registries in question I strongly disagree.

If you want to delay this fight to the IANA allocation time, that is
fine by me, but I will point it out already now that I will be against
allocating separate code points for each protocol as there is no need
for that.

> Adopting the rest of the framework would be a useless exercise.

Keeping the IANA registries clean is important for me, in addition to
make it easy to implement multiple methods in the same implementation.
I do not consider them as useless resons. Especially as it only causes
very small changes to the actual protocol drafts (I would expect less
than an one hour of work).
