    Stop supporting fallback between SSH versions.
    
    The UI now only has "1" and "2" options for SSH protocol version, which
    behave like the old "1 only" and "2 only" options; old
    SSH-N-with-fallback settings are interpreted as SSH-N-only.
    
    This prevents any attempt at a protocol downgrade attack.
    Most users should see no difference; those poor souls who still have to
    work with SSH-1 equipment now have to explicitly opt in.
