It would help if you'd tell what changes in how region works you are
alluding to.  I use Emacs for the last 30 years, and the way region
works for me didn't change at all, AFAICT.  So I'm really puzzled by
what you say here.

Emacs doesn't change such basic traits of its usage, either.  We
haven't changed the command-line options, didn't change the documented
APIs of Emacs primitives in incompatible ways, and '+' still adds,
doesn't subtract.  However, Emacs has several orders of magnitude more
features as aspects than the likes of cp and mv, and as time passes
and the Emacs audience changes, the popular demand for some of them
also changes.

In any case, whenever a backward-incompatible change happens, there's
usually a way, called out in NEWS, to get back old behavior.
