I disagree. I think the glider used for training should spin like a

A benign glider significantly increases the chance of survival,
doesn't it?

On the same principal training gliders could be fitted with elevator
backstops so that pupils could pull back as hard as they liked on the
winch with no danger of stalling.

How about watching the airspeed? If you maintain a margin over the loaded
stall speed, there no chance of stalling.

As for the ASK-21, you don't gain anything from pulling back anyway. The
highest winch launches are when the glider is flown at the best L/D angle of
attack - that's about neutral elevator..
