Also, to be clear, I said to deprecate them, not remove them.  I agree
that, unfortunately, it would be very difficult to remove them and
their associated complexity without causing loading problems of older
files.  Although if they are deprecated for long enough, hopefully we
can then remove them in the future (although at that point one hopes
we could just develop a more modern transform system anyway, that
would cover these cases as part of a well thought out and elegant
design rather than as a mish-mash of corner-case features).

And when I'm speaking of complexity, I'm largely speaking of internal
complexity.  Code maintenance.  Covering corner cases that weren't
originally envisioned.  Making it harder to add features that _can't_
be accomplished already by other means, such that everything works
together/isn't buggy.  Etc.

I'm not going to kick or scream to keep this out.  As you say, I can
simply ignore it if I don't want to use it.  But I think there are
good reasons to leave it out.  Specifically, the benefit provided to
the user is extremely minor, it doesn't enable anything new, and it
looks like there are some pretty major code changes in there
(admittedly, I only glanced through it).
