Coming from a gliding instructing background, I can only concur the stall/spin recognition/avoidance/recovery is at least inconstantly, if not badly, taught.
BGA instructors are rigorously coached in stall spin recovery in all kinds of configurations and loadings at heights down to below 1000ft (some demo only).
There is a particularly nice one which involves stalling/spin entry in under and over ruddered turns and works really nicely in a C152. All my PPL students get to see it and have a go.
From my perspective the ‘spin avoidance only’ teaching is a bit of a cop out –possibly engendered by a lack of suitable available aircraft.
