I knew a guy who used a different color scheme for terminal sessions connected to production servers, so he didn’t do something in the wrong window.

A guy. One. How many people have I met with shell access to production servers?

I have all hosts share the same .zshrc and config with yadm, so all terminals look the same and share keyboard shortcuts. My oh-my-zsh with powerlevel10k is configured in a similar way: when I'm connected by ssh to a host it shows hostname@domain or hostname@ip on RIGHT side of a screen. It's not much, but it's easily visible, sometimes even annoying, but at least I never deleted wrong docker images from dev :)
