Note that although I believe we do need to sort out this mess, and having something like backlightd would be a good idea, I likely won't have time to work on this in the near future. For $dayjob I will be focussing on finishing rootless xorg and working on libinput. And $hobbytime is all going to getting upstream support for Allwinner ARM SoCs into place. Still I'll put a line about this in my todo file, just don't expect anything soon, and no promises about this at all!
