that is up to the shell protocol extension. wl_shell.set_fullscreen and
zxdg_toplevel_v6.set_fullscreen have an output argument. If you have
pre-defined set of applications to run, you could also write your own
shell extension instead.

The DRM leasing protocol for Wayland has not yet been written, AFAIK.
