I've been trying to come up with a hypothetical use case for this. I can't use this as a server without keeping an active session right? I wonder if you could get around this by sshing into itself from inside the primary session. Is that an edge case you've considered?
Maybe this and other future extended features could be configured via some host-accessible mounted conf.d? Otherwise if I forget to use that command on every login, I might just forget, logout, and go on thinking my server is still running.
