Right, but until Gtk + Wayland offers the same feature parity and 
customization as that of Gtk + Xorg, there will be distros/users that 
will keep it alive.

Doesn't look like it is going to happen anytime soon given the massive 
pushback.

It looks a bit similar and interesting but one difference is that our 
feature uses monitor labels such as DP-1, HDMI-2 which is a bit more 
intuitive. And, the other key difference is that our feature includes 
"hotplug" functionality where a Guest display/window is deeply tied to a
physical monitor to make it appear to the guest that it is dealing with 
a real physical monitor.

In other words, when the physical monitor is unplugged, the associated 
guest display/window gets destroyed/hidden and gets recreated/shown when 
the monitor is hotplugged again.
