In that case, nobody would be tricked because they would have to explicitly select that package. Those already having screen installed, or selecting screen for installation, wouldn’t automatically be upgraded to tmux-as-screen. So what the comment you replied to mentioned as a problem of inertia and there being “no immediate incentive to switch” would remain largely unaddressed.
Well, I guess the other part would be removing screen from the official repo. So the original utility is gone, but we have a compatibility package you can install that should make things work like they used to. (Of course, if you really still want screen you can build from source or some such.)
