I also quiet like transient-mark-mode, despite the fact that at first I
disabled it most vociferously (in the confines of my then office).

I would like this behavior to have a customization variable.
highlight-region-on-exchange-point-and-mark.

Well, I don't use C-x C-x, I use C-u C-SPC, but maybe I'd like to bounce back,
and in that case having the region re-highlighted seems... odd.
