Agree, but what do you make of the stall warning ...
Let's say you want to practise a full stall exercice on a 757, would you still trim up past the initial stall warning ?
The question is why the automation is doing something you would not ?
That the low speed stability protection disappears in a scenario of unreliable airspeed is logic, but also auto trim should.
