I played with it for 10 minutes, very impressive. Couldn't get vscode to work, will try again later with different apps. (vscode is not that important anyway as it has a remote mode)

I understand (well, "guess" more than understand when it comes to graphic stack in Linux) that it being it's own compositor probably means running a full desktop environment in it is infeasible, but a good way to run software remotely is painfully missing in Linux right now, even one app at a time. The built in servers in kde/gnome are problematic in general and require the monitor to be turned on.
