Fair enough.  Do these redundant, unnecessary tags actually need to be
listed or "marked" anywhere, since they will be defined by the
generative grammar?

The draft talks about such tags being "marked as 'superseded' by this
document."  It's not so much the word "superseded" I'm thinking about as
the "marking" mechanism.  Under RFC 3066bis, one could say az-Arab or
az-Latn (formerly registered tags) just as easily as en-Latn or en-Kana
(never before registered or valid).  Does the registry need to mention
the existence of formerly registered tags that are now part of the
grammar?  What would be the benefit of doing so?
