Yeah, this is how I do it. If it's a reasonably modern remote image you even get color highlighting. And in a way, it lets me segregate, "on this host, I'm working on this project, on this host I'm on this project, all the state/context is there when I re-activate my tmux ready to see what's up.

If I'm writing a lot of code or doing a refactor needing more thought, I'll do it locally, to be sure.

I even started baking emacs into docker images we use for running debugging tools in kubernetes environments. Can quickly edit and run little scripts to do admin and operations and debugging tasks.
