Hi,
What we don't know is the number of times where that design decision may have helped in a situation where the flight envelope was not compromised in such an extreme manner.
Personnaly I prefer work with what I know ... instead with what I don't know..
What I know is that the AF447 ended in the sea and it's possibly an (minor) design implication to add to the fact (major) of the incapacity of the pilots to fly the plane in a professional way ... (pilot error or unconscious action)
