That's not how the real world works, and you should know that by now.

consistency problems aren`t the issue here, though of course if there's
any bug in the current CVS that would cause it to trip over the extended
non-standard metadata then such issues would instantly arise.....

Excuse me? Everyone _should_ care, and I for one certainly care an
incredible amount. I was only placated into accepting the integration
of RCS management inernally to CVS because it meant there could be an
incredible boost of performance in some circumstances (eg. those where
multiple external operations were previously required). I still worry
about the differences in implementation and the supposedly innocuous
differences in resulting RCS file contents. If I'd had the time I would
have contributed code and tests to ensure that CVS produced ,v files
indistinuishable in every way from those produced by doing the same
operations with plain RCS. Maybe someday someone will still get around
to doing this.
The fact that CVS is simply a wrapper for RCS (even if only conceptually
now) is one of its major features! (and it's not just because you can
move RCS projects easily into CVS -- but also the other way around, and
not just back to plain RCS, but to other tools that might use RCS as an
underlying repository structure)

Well, it depends, but that's not really the issue.

Anyone with any long-term investment in CVS _should_ care.

Of course -- that's the problem because the new, and in this case
incredibly important, metadata is effectively hidden from its view.

Of course -- and that wouldn't be as big a problem if it didn't affect
the fundamental structure of the repository.
(or perhaps you don't care about the renamed files when you go to
recover your CVS repo and/or convert it to some other format?)
yes CVS won't go away or be unusable in the same way that could happen
to commercial software, but that doesn't change the fact that RC

That's where you're going wrong in your thinking here I think.
Yes during production CVS repositories should only be modified by CVS.
However that's not the only concern of anyone with an investment in a
CVS repository.
