Yeah, good catch.

I'm inclined to change this to "updates" rather than "obsoletes".  It's
otherwise a lot of stuff to copy over just for the sake of making keeping
this as an omnibus document.  I'll do that unless someone makes an argument
for the other choice.

Are there any registry entries you think that should reference both
documents?  IANA lets us do that for registrations for which an implementer
should be pointed to more than one reference.
