That's unfortunate, yeah.
I think that my main point is the fact that tmux runs locally only
implies that support for this kind of proxying does not necessarily
belong in tmux itself. There are all manner of solutions which
could be imagined that involve no tmux support. You could start
tmux with an ssh-agent that can be pointed, you could play with
symlinks to local domain sockets, you can start tmux under a
standalone X11 proxy that can repointed, etc. None of these require
tmux to support anything. And you have this luxury because tmux
is a local application. There are likely X11 proxies already that
one could use with tmux.
I think that this kind of proxying in tmux would lead to lots of
unnecessary memcpy(3)s, unnecessary code complexity in tmux, and
more implementation dependence. And I don't think that any value
would be added in the process.
