That would also not be accepted. You don't get to rewrite output like
this in old CLI tools that have had consistent behavior for decades. It
causes breakage for systems expecting old behavior, even when that
behavior is unfortunate and wrong. You just build different, better
tools, and convince users to switch over. In this case, that tool
exists and is called xrandr.
