I agree with Gerd on the discoveries.

H= ere's some code how tmux works with that [1], we can probably avoid it = by providing a frame-local flag which enables the functionality, so that mu= ltiple emacs clients might be connected from potentially different terminal= s.

We can improve the default value of the flag based = on terminal capabilities later once we have confidence in the way it works = and probably extend it to support different specifications of syncing.

Yes, that looks like them.

Not even that.=C2=A0 I tried to find something today, but nothing useful turned up.

Yes, something like that, I guess.
