The big thing in all of them was "touch" or "feel". The plane talks to you, and those who do not listen or cannot listen will pay the price, regardless of what the indicators display or the control system is designed for. See the AF447 threads.
Gee, I would agree in principle, but even minor cross-control (uncoordinated flight) could rob the pilot of a warning buffet. I learned that lesson in a few memorable seconds in an old PT-22, fifty years ago. My instructor asked for a stall with about 1/3 rudder, and we did the prettiest snap roll
with NO buffet warning, only a knot or two above Vso.
