I was just highlighting the fact that un-stalling doesn't require an aggressive control input. If you need power then add power. If you need full power than use it.
the PhD and Test Pilot School are the only courses which covered that material, and I'd venture it's a bit much for PPL.
You make it sound so difficult. If the average PPL can learn effects of controls in the upright sense, why should they not be able to do it in the inverted sense, or when in a spin? Surely having some understanding is better than having none at all.
