Hi,
I'm glad someone finally tried it.:)

However, I wonder how you could receive this focus-in event:

Because it don't work for me in dwm either.

Let's make more detailed test case:
  $ sudo pacman -S st dwm # Actually: st-0.6.3, dwm-6.1-3
  $ cat ~/.tmux.conf
      set -g default-command /bin/bash
      set -g focus-events on

In dwm:
  - A-S-<Enter> # to launch first _bare_ terminal
  $ st # to launch terminal from another
  $ tmux -L test # independent tmux server
  $ printf "\e[?1004h"
  - <C-v>
  - A-j/k

Results:
    - cursor slightly blinks, which indicates focus lost/gain
    - but nothing printed (no focus in/out events in tmux)
    - however on splitting tmux C-b % those events immediately shown

I will look at it by curiosity, however if you really could make it
work on your accord, then it's not strictly related to problem.
