Yes, I hope we incorporate (or invent) only behaviors that make sense
and improve editing.  And in this concrete case (or, say, comment-dwim,
M-;), I actually like this special behavior.

Well, there's no way to be *not* at the boundary of the region, right?
So there couldn't be any special behavior if at the region boundaries
any command had to act "normally."

I deactivate the region (C-g), delete the character (DEL), and
reactivate the region with `C-x C-x'.  But this situation occurs (for
me) much less frequently than the situation where I want to delete the
complete active region, so I'm happy that I can now simply hit DEL
instead of C-w.
