Has this been discussed with Wayland developers? Framebuffer device 
access can possibly be abused to take screenshots and draw on top of the 
compositor in a Wayland-based environment. Impossibility for arbitrary 
applications to take screenshots was one of the design goals of Wayland, 
and this change breaks it.

So, unless one of Wayland developers confirms that they are OK with it, 
please revert it and ask for a CVE.
