Honestly, making this optional isn't really interesting. It's just code
complexity for very little benefit. Especially when you look into the
service stop functions.

If you could do a full replacement of *all* existing functionality used
in screen with tmux, that might be. Screen -X stuff has some interesting
failure modes on loaded environments, and I'd be in favor of switching
to something else that didn't. However in looking through tmux man page,
I'm not sure I see the equivalents to the logfile stanzas.

I'd like the blueprint to address all the screen calls throughout the
codebase before acking on whether or not we'd accept such a thing.
Because the screen use is more complex than you might realize.
