mosh is an infinitely better user experience for certain use cases, particularly poor/intermittent connections. session establishment is very slow and requires a lot of round-trips, and if you have high latency and packet loss, it becomes painful. if you establish a session once with mosh, you don't have to establish connections after that, you just blit UDP packets.

mosh on its own doesn't handle scrollback buffer. So you're back to tacking on other things like tmux on top.

Those three are only neighbours to maintaining ssh connections problem.

You can run those on the remote side of the mosh session
