While point is always visible, mark can be out of view, so the region
need not be fully visible in the selected window.  But more importantly,
using the minibuffer provides a smoother and more consistent UX compared
to an additional yes/no question, IMO.

I think it makes sense to have an option that is sensitive to the size
of the region, although personally I'd probably stick to "always ask",
especially if the prompt for confirmation isn't too obtrusive.
