I may have few changes to it not posted to the list, but I won't get to them until next week. And the interaction with the surface/output scale (HiDPI) really needs to be figured out. I don't mind if someone takes a shot at this, since I'm still away for a week, and uncertain of my immediately following schedule. I'm not aware of anyone else working on it, but then I have been pretty ignorant of Wayland discussions in the recent weeks.
