extremely rapid control input may do the same

Probably not for most aircraft but certainly a potential pitching problem in aircraft with very high pitch rate capability where a vortex can be established on top of the wing with a significant overshoot of the normal stall angle.
When things don't break, the alternative may be an out-of-control flight mode that is totally foreign to the pilot, and may in fact qualify him for a Guinness Book "first"...

Take, for example, the old T-2C Buckeye USNavy trainer jet. It was so docile in stall/spin manners that it was used for out-of-control training for ALL Navy tactical jets. Virtually ANY spin recovery procedure from ANY airplane could be used to get out of a spin in the T-2.

To illustrate "the alternative" created by rapid control reversals, the T-2 did a VERY nice Lumczovak (sp?) -- an inverted, 3-axis, autorotation [spin]. Combine a rudder triplet (rapid full reversal with another one added) near stall speed with cross-controlled stick, and away you go! In that airplane it was recoverable IF the pilot had enough sense to apply recovery controls; in other airplanes, recovery may not be possible...

So, maneuvering speed USUALLY keeps you from breaking the airplane, but ONLY IF you keep it flying as well!
