Split into 3 different utilities
- xwayland-run, to spawn an X11 client within its own dedicated Xwayland rootful instance,
- wlheadless-run, to run a Wayland client on a set of supported Wayland headless compositors,
- and xwfb-run, a combination of the two other tools above which would be a replacement for xvfb-run specifically.
