Dedalos put it rather nicely, Karnak.
No P-40 fans are requesting super uber flappen (TM, patent pending). It's just they get damaged first time, almost every time. It would be like taking a bullet in the cockpit and losing one of your elevators. It's an oversight or throwback to older damage coding, and we just want to see it brought up to the higher standards of the more recent additions.
That is all. Nobody is advocating it should turn with zekes or the like.
