What you describe is they way it should work.  But it actually does
not work that way.  It actually works the way I described in the part
that you conveniently deleted, so here it is again:

|For getting rid of a word, you don't even need to make an RfD; someone
|proposes to make the word obsolescent at a meeting, without providing
|any numbers on usage or anything, the committee takes a vote, and the
|word is obsolescent, and will be gone in the next-but-one standard
|unless there is a concerted effort to keep it in, as happened for
|FORGET (and even then the committee decided to keep it obsolescent, so
|the fans of FORGET may have to make the same effort the next time).
|This has happened to LOCALS| and [COMPILE], and almost to (LOCAL).

So while parts of the committee are extremely reluctant when it comes
to adding new words (because it is supposedly so difficult to get rid
of them), the committee is quite keen on making words obsolescent
(which leads to deletion from the standard in a later version), and
does not do any research about the usage of the word in applications
before taking that decision.

A nice example is LOCALS|.  It was added in Forth-94, and was not a
good solution, so it was declared obsolescent in Forth-2012 and will
be removed from the standard in the next version.  This was not at all
difficult.

What actually is difficult is getting a de-standardized word really
out of use, as we have seen in occasional discussions of NOT.  But
such problems can just as well occur if the word has never been
standardized; example: "{".
