This is partly issue, but it is not issue we need to solve here, as
this document is not something that should obsolete 3947.

Also 3947 only defines extension for the IKEv1 (RFC2409) and that is
already obsoleted, so effectively RFC3947 is already obsoleted, as
there is no way to implement 3947 without implementing obsoleted
protocol...

This issue is not not important enough to require RFC now.

For now I would just leave it as it is, but fix the references in the
IANA registry so that document will not be referenced, especially as
the original IANA reference was not to the correct RFC in the first
place.

That is true, but as this document already modifies the TCP/4500
reference, fixing the UDP/4500 reference at the same time is not
completely unrelated fix. 

Obsoleting RFC3947 would be unrelated fix.
