Well, two reasons. One, because there is no guarantee that you will
reach stability in a bank without exceeding Vne (and in fact in many
airplanes you will not - wings or tail will come off). Two, because
recovery from a spiral dive actually takes a fair amount of altitude,
and trying to do it quickly will likely break something as you will be
well above Va.

Well, OK - but it's not a technique at all. It is simply a
demostration that the airplane will not remain wings level at trim
speed without pilot input for very long, expecially in the event of
engine failure. Quite the contrary, an active recovery will most
likely be necessary.

If the demostration is wrong, then the plane WILL remain wings level
(the way a ram-air parachute will). Now THAT would be useful for
inadvertent IMC encounters. Just tell people to let go of the
controls, and the plane will fly out of it. In fact, that is exactly
what parachutists do if they inadvertently encounter a cloud.
