Yes nano has a good use case since an editor is pretty much mandatory to administer a server. And since we all had to start somewhere most of us I am sure used nano at some point.

A terminal multiplexer is not mandatory at all to work on a server, so I wonder who would use a terminal multiplexer and also wants to see the basic commands at all times.

I would, as I don't have the time or patience to remember all of tmux's commands. For a command line text editor I also use micro, which has sane keyboard shortcuts out of the box.
