Surely one of the common precursors to "loss of control" is disorientation. In which case it is unlikely that a disorientated pilot (eg in IMC, low level downwind turn etc) will be able to recognise and recover from a stall if they are disorientated enough to get into the stall in the first place.
Yet in the briefng I see lots of nice colourful pictures with wiggley lines and no explanation of why you would end up there/prevent ending up there in the first place. Then in the training sequence, some instructors will suddenly whack in all sorts of control inputs such as the OP has mentioned leaving some students wondering if the aeroplane has a mind of its own, because otherwise how could this situation arise on a nice day with a good horizon?
I you read the syllabus carefully there is no requirement for wild control inputs in order for the student to be found competent in stall recognition and recovery,
