I personally would, because learning less tools is great.
I've had some problem applying this principle when using tmux locally on a system with i3. You kinda need to be consistent in which of the 2 you use to create new shell windows.
Isn't the emacs philosophy to never leave emacs? Doesn't using tmux go against that? Or do you run tmux inside of emacs?
I use spacemacs and coming from vim, its taking some getting used to but I'm still always trying to do more things in emacs and not switch to my terminal workspace.
I feel spacemacs is just a vim clone with really bad cpu and ram utilization. If I am going that road, why not use an ide like eclipse or visual studio instead?
If chrome ran within tmux, that would totally be my approach. Sadly, there remain GUI's that are better than TUI's (or rather: sadly tmux can only multiplex TUIs).
