I'm a bit lost. I use my dotfiles for this.

If it is a machine I control: I control the terminal so there's no issues.

If it's a machine I'm sshd into: that's my explicitly stated tmux case right there.

If it's a machine I don't control: well I can't do anything anyways, so conversation is moot. This situation is exceptionally rare though (where I can't even do local installs)

I agree that you should use what works for you, but I'm curious what you're getting that isn't already offered by your system
