While an OpenWF back-end compositor for Wayland once provided hope that more hardware would work with Wayland whereby OpenWF Display drivers were available, the OpenWF support is being dropped already from the compositor.
The OpenWFD back-end is being removed that implemented the OpenWF 1.0 Display specification, which is a Khronos Group specification for governoring the display control hardware with mode-setting on displays, display discovery, direct pipeline control, and other functionality in a standardized way. OpenWF was released in 2009
, but hasn't seen too much widespread adoption.
The OpenWF Working Group did offer help to Wayland developers
, but this back-end is now being removed over lack of maintenance. There aren't any upstream developers working on the OpenWF support in months.
Dropping OpenWFD was brought up on the wayland-devel list
