Assuming that everyone eventually catches up, this should be a
short-term issue. So, all we have to do is figure out how to make the
transition, which seems a lot less weighty than something that will
affect the environment for a long time.

We need to consider the cross-version compatibility issues for both the
window system and the kernel. That means an old window system with new
kernel or new window system with old kernel should work as well as it
does today.

Today, an HMD display is presented as a normal output and applications
can discover it through the window system and present an image on it by
placing their image at the right location on the screen. To keep that
working, we can't hide HMD outputs from an older window system.
