Hi Bejnamin,
If you get the green light to break the user space we might as well  
think about getting it in line with led/oled over bluetooth (intuos4  
wireless) or the other way around.

The biggest user of led/oled functionality is gnome and there are also  
a few small projects that would stop working after that change. I can  
fix i4oled project easily, i4oled-gui is based on gnome handling oleds.

Patching those 2 should be enough to fix gnome:
https://git.gnome.org/browse/gnome-settings-daemon/tree/plugins/wacom/gsd-wacom-led-helper.c
https://git.gnome.org/browse/gnome-settings-daemon/tree/plugins/wacom/gsd-wacom-oled-helper.c

Regards,
Przemo Firszt
