Yes, but open files and in-progress requests are lost at reconnect.

Sure. Obviously one of the drawbacks of a stateful protocol is that the server state can't survive a reconnect.
But that sort of reliability has never been the goal of sshfs. And even if that was needed, it could probably be much better handled in a lower layer.
