I believe I see your point. 

We have already passed this way with RFC 9370, which renamed some IKEv2 registries.
One may argue that RFC 9370 is more kind of mainstream document, than this draft,
but it is still not for every implementer (some may ignore PQ stuff). 

Thus, I don't believe this is a real problem, especially if IANA registry page will 
contain notes describing the fact of renaming, the old names and the document
that caused it (as it was done with RFC 9370).

If you think that I'm still missing your point, then may I ask you to exemplify
the prospected scenario when a careful implementer would be confused.

Regards,
Valery.
