It depends. I could see myself using this for niche applications such as visually marking certain terminals.

When you work on multiple remote hosts, it's common practice to use different profiles to visually identify hosts. Say your local machine has your standard and preferred colorscheme but staging machines have a green background and customer-facing machines have a red background. Indeed, it's a manual process but I've seen people use it in most places where a substantial amount of work is done on remote hosts (I still use it today if/when I need to access remote hosts).

I deleted an archive tape, by being logged in to the wrong machine. The terminals did have different prompts, but that wasn’t enough.

It's happen to all of us frankly. Now I also keep the default shell on remote machines. I guess it's a cognitive trick where I feel uneasy at the different prompt and key bindings (I use zsh with bindkey -v locally).

For me it's the colour of the tmux status bar.

Same.

  echo 'set -g status-bg brightmagenta' >> ~/.tmux.conf && tmux source-file ~/.tmux.conf
