Hmm, I think the module should only reflect the registry contents, so
any problems should be fixed in the registry first.

Actually, I copied the corresponding text from RFC 7224, but I am not
sure whether the deprecated status is used at all in IANA registries. If
not, we can remove that part and leave only "obsolete". Unless somebody
knows the answer right away, I will ask IANA about it.

YANG doesn't define experimental status (maybe it should).

Yes, this would be a good thing to do. I assume that "historic" can be
interpreted as obsolete. BTW, the semantics of the status terms in YANG
is defined here:

https://tools.ietf.org/html/rfc7950#section-7.21.2
