Who's talking cables and vacuum gauges, what is needed is humility as our system, logic, sensors will never be 100% accurate and reliable so we provide a simple switch to get rid of any protection or automatism if required. Yes, you the pilot may have to protect the airplane from our protections ...
If a 320 pilot needs regular practice before flying simple direct law then something is obviously wrong, what happens the day the elevators quit ... ?
And AF447 would have been much better served with direct law than any other law ...
