So, with Wayland none of these will work. Even with XWayland one
applications root window is not accessible by another application (by
design). Whilst I agree that the current specification is super
unclear I don't think adding more root window atoms or output
properties when Linux is very much transitioning to another
incompatible display framework is useful.
