Any Wayland compositor running atop kernel 4.12 or later and handling the "link failed" uevent correctly will also be compliant. It's that latter bit that's difficult, and that will have to be checked on a compositor-by-compositor basis.

The newly added link-status property that gets exposed to the userland, should be used in Wayland and acted upon when its set to BAD to request a new modeset in order to make it compliant.
I plan to write a detailed article as a follow up with some examples to help scale this solution to other userspace drivers like Wayland, Surfaceflinger etc.
