I can understand where Dave is coming from, from a kernel pov, so this might really be easier to just solve in userspace. I don't know if you've seen my very rough sketch of how this could work in userspace in my other mail. The idea would be to still make this show up on a specific connector, 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.
