| Well, X11 is a protocol, not a device, either.

Point taken.

Booted an older laptop using 22.04, selected 'not X11' in the gdm dialog but
the same Gnome Menu still says Windowing System: X11.  So I am no longer sure
how I would convince myself if I am under Wayland there or not.  The answers
in https://unix.stackexchange.com/questions/202891/how-to-know-whether-wayland-or-x11-is-being-used
suggest I still run X11 too.  So I got nuttin' here.

In any event, I read OP as asking 'do we need a new device' and I still think
that the answer to that still is 'likely not' as the X11 compatibility layer
should cover this.
