Is it mixed automation?
Maybe it's more back-up/redundancy which improves....safety.
In ARM mode - apart from excessive wind gusts when consider disconnecting as discussed - the A/T will only engage if the pilot
up and allows speed to decrease towards the stall.
And that's only after it flashes a warning for a while to alert the pilot of what the A/T MIGHT have to do if the pilot doesn't correct THEIR error.
A system that tries to prevent the aircraft from stalling if the pilot gets distracted - mighty dangerous piece of equipment, better not use that!
At any stage - regardless of what systems are/aren't being used - the pilot has an obligation to make sure what should be happening IS happening, if not then MAKE it happen.
If pilots decide NOT to make things happen....well that's a whole other thing.
