This is a good idea, but difficult to implement.  The face code is
already pretty darn complicated.

You're the only one who's complained about the region obliterating
font-lock, so I don't know how widespread this feeling is.  Maybe
others who are against tmm can chime in about whether they feel
strongly about this?

If this is a "big" objection, here's an idea: make the region face
specify only the background.  Try this (colors chosen as example
only):

(set-face-attribute 'region nil :foreground 'unspecified :background "#333366")
;; for dark backgrounds

(set-face-attribute 'region nil :foreground 'unspecified :background "#DDDDFF")
;; for bright backgrounds
