SSHFS provides enormous value precisely because it doesn't rely on configuring a file server or elevated privileges. It's convenient, secure and performs well. The ability to create ad hoc mounts for any remote location I can access via SSH is awesome (though I prefer rsync or scp for file transfers).
But relying on SSHFS in production... Yeah, that's insane.
