History matters, Drew.  AFAIK you don't prefer the current binding to
a rectangle function, but want the key sequence left for future use.

"Reserved for future use" is not really on the table here, given a
twenty-year history for one of the bindings.  Not everybody is going
to upgrade to the latest and greatest Emacs (eg, about 50% each of two
different corporate samples I've seen, both over 200 users, used
Emacsen released more than 5 years before the dates of the surveys),
but they do sometimes share others' Emacsen.

At least in my experience debugging sessions are more likely to end up
"hands on" than coding sessions; this is a binding that matters.
