If figuring out how to have two specs is too much hassle, you could
probably get 90%+ of what people are looking for by putting all of the
normative stuff in the CORS spec and writing an informational note
describing UMP that only discusses the subset of CORS needed for UMP.

User agent implementors will have to read the CORS spec regardless of
whether or not UMP is in it or a different spec, so creating two specs
doesn't help much. And, as others have noted, service developers and
web authors don't really tend to need to read the specs, so an article
would probably be sufficient.
