Pannable virtual desktops/canvas in kwin/wayland

One of the old features of X11 is that we were able to create a larger virtual desktop on a dummy output, and then decide where on that larger canvas an actual monitor would be.

Is this something that’s doable on wayland? The end goal would be to create a large virtual desktop using AR glasses with accelerometers, as discussed here: [Discussion] Large virtual desktop in linux/wayland with head tracking · Issue #23 · wheaney/xrealAirLinuxDriver · GitHub

In theory, we’d just need to hook up the sensor data to allow panning of the larger virtual desktop to align with head movements, but I’m not sure if this is something that needs a Wayland extension to allow this, or some changes in Kwin, or both (or none).
