It isn't.  Given what's in 6761, I doubt the question ever came up.

Well, the list of names in the root is nominally an IANA registry, and
they're removed lots of names such as .NATO and countries that no
longer exist such as .CS and .YU.  But somehow I'm guessing that's not
what you're thinking of.

It is my vague recollection that we have removed some old cruft from parameter
registries, but after some googlage I can't find any details.

R's,
