Recently completed a turbo prop sim re-currency in the US. Stalls are now done as 'scenario based', different configurations, distractions (head down doing paperwork, multiple ATC clearance changes, etc...), including one at 200 feet on approach. I found this type of stalling far more beneficial than anything I had done in an aircraft at 3000/5000 feet.
This is what a simulator should be used for. Even the aircraft based stalling lesson should be based on possible scenarios after the basics are done. Especially around landing stuff ups where the nose is too high, high drag after a bounce or balloon, or results of tightening the turn to final at too low a speed. These are not things you would want to practice at low altitude in the real aircraft with low experience pilots. The whole point of these exercises is basically a warning to stay away from these scenarios as they can bite hard.
