I just tried the following:

Terminal 1:
$ tmux new -s mysession

Terminal 2:
$ tmux -C attach -t mysession
split-window
split-window -h

And as expected, in Terminal 1 the window got split first vertically,
then horizontally. However, in version 3.1b Terminal 2 was echoing the
commands from Terminal 1. This doesn't happen with version 3.2
anymore. I verified by building 3.2 in WSL 2 (Ubuntu 20.04) and there
the echoing does work.

Just out of curiosity: is this a critical feature for you? E.g. are
you automating tmux with it? Because as far as I understand control
mode is intended for integration with terminal emulators. And so far,
iTerm2 on Mac is the only one implementing the protocol.
