Do any Wayland compositors implement virtual monitor features?

[robertkirkman]

Some X11 window managers (AFAIK only openbox and marco) support the xrandr --setmonitor command, which makes the following possible (while perfectly preserving all OpenGL, Vulkan and Glamor DRM GPU acceleration functionality for Intel and AMD GPUs) on all systems using Xorg + openbox:

• force all windows to maximize and fullscreen (provided the window's app normally allows maximizing or fullscreening it respectively) across only an arbitrary subsection of one monitor instead of filling the entire monitor
• force all windows to maximize and fullscreen across an arbitrary amalgamation of multiple monitors instead of only filling a single monitor at a time

A basic example of using this functionality is on the Arch Wiki.

As far as I have been able to tell, no currently existing Wayland compositor has had either of these features added to it. Could this be added to the "Missing" list, or is there a counterexample?

The "window" concept from X11 does not technically apply to Wayland, so in this context I mean the closest direct Wayland equivalent, "toplevels".
