This exactly. While on the visual side I prettified it a bit over time, Initially I was really tempted to do some major keybind remapping, having used lots of GUI terminals like Terminator in parallel, especially the infuriating h/v splits that I still routinely confuse after years with tmux, but I stopped myself so as not to cripple myself when I log in to anything that has tmux running defaults - and I'm happy with this choice.
