If you have to read two RFCs in order to implement IKEv2, having some
duplication between them doesn't help anyone. And having differences
between the two RFCs for the same values is exactly wrong.
What you are proposing is exactly one of the mistakes that we had in
IKEv1 that we said many times we wanted to avoid in IKEv2.

This isn't the way that the IETF works. New registries get
established by RFCs that have values in them, and then can be
expanded based on the rules established in the RFCs.
