Thanks! Interesting to read the rationale behind it [0] which in short is, try not to use what is basically a terminal emulator within a terminal emulator, and window management should be done by the terminal emulator. I primarily use tmux for session persistence (in ssh sessions) anyhow, and still default to my muscle memory for new tabs/windows in the window manager. I haven't tried it yet. The proof of the pudding will be in eating it I suppose.
