An excellent, excellent question.
The bottom line here in this entire discussion re: AB fbw, is that it is highly functional in virtually all its iterations when confronted with straight forward challenges to remaining in the air.
If no one else has figured this out, the problem arises, as it does with ALL aircraft, when the monkey grabs the football.
Airbus have this less figured out than other types, and their arrogance in admitting to it is still killing people.
Abnormal situation requires abstract and intuitive action.
NOT ALTERNATE. Bowing to ALTERNATE solutions is killing us.
We don't need ALTERNATE, we need CUSTOMIZED.
And CUSTOMIZATION comes from the cerebellum, not the thirty year old chip, programmed by people who still do not "get" ABNORMAL.
One cannot anticipate that which he has no experience with.
