That's exactly what I meant by "make C-SPC not activate the region".

I'm not interested in discussing what options we should provide: that's
a trivial issue compared to the issue of what should be the default.

That means it activates the region, which is a problem if the user just
wants to swap point and mark but not activate the region.

Again, options are of no help here.  We're discussing the default.

Did I say we're discussing the default?

Emacs should first do no harm.  I.e. the region should only be activated
when the user really intended to, since it may then be deleted
by a mere DEL or a self-inserting key.
