They’re great systems but they aren’t perfect.
Agreed. And the other problem with using A/THR for asymmetric approaches on a FBW Airbus is the lack of thrust-lever ("throttle") movement with thrust changes. (We lost that argument with AI in the mid-1980s.) So resting your hand on the throttles provides no tactile warning when the A/THR changes the thrust.
Can't speak for others, but my simple brain was just about capable of remembering that if, for example, the R/H thrust lever is going (or being driven) forward, I'm going to have to consider pushing my right foot forward a bit too.
