but only at the xrandr level, not at the drm level, and have the xserver
talk to some kind of backlightd for this.  The backlightd API should of cource
be generic enough that it can be used in wayland too.

Sure. You should probably take a look at libbacklight, which already has 
some amount of support for appropriate heuristics.
