Exactly! Like if I'm admining a server what am I supposed to do? Message on a big slack channel and have everyone ignore me? It's easy when people are just logging in through normal ssh as I can put a big bright warning message on their screen that they can't ignore.

Also, timeouts...

Also, does anyone know if VSCode supports mosh?

Could just put this in /etc/bashrc.

    if [[ $TERM_PROGRAM = vscode && -f /etc/motd ]]; then
      cat /etc/motd
    fi
