The proposal has the property of being straightforward. I like that.

But this doesn't seem right: we're not going to have one such variable
for delete-backward-char, delete-char, delete-backward-char-untabify,
and the handful of other commands that
grep "'delete-selection 'supersede" lisp/**/*.el
indicate will want a similar treatment.

the other problem here is that this change also affects calls from Lisp
rather than only interactive calls.

PS: We will want to remove mouse-region-delete-keys and related code
ASAP since it is at the root of various known bugs (mostly due to the
fact that it delays the end of the mouse-selection commands to the
beginning of the next command, so post-command-hooks don't get run at
the expected time).
