You should anyway run mosh+tmux. Not sure about this though, ssh still disconnects and you have to reconnect and then launch tmux attach again. I agree it doesn’t seem like much, but just opening any device and continue from where you left off without any extra interaction feels great. It is kinda like auto save on iOS, you could argue that pressing the save and open button isn’t that big of a deal, but once you experience it the experience changes completely.
Any reasonable ssh client should be able to reconnect to a tmux session without any interaction. The benefit of it being instant is certainly nice, but I'd still classify it as minor, especially since forced disconnects are only really a problem that way on iOS.
