We did put a "pop stall" function into ours, but it was only related to bleed valve malfunction. In UK we don't get pop stalls normally, and since training time is a limited resource, it is best spent on feasible scenarios. Anyway, most folk are aware of the possibility of pop stalls when landing on the Ninian, but it was more prevelant on the AS 332L and so is ingrained in 30+ years of experience.
Ultimately I don't believe you can train robotically and unthinkingly for every possible scenario. What you can do is train for a set of tools to be used intelligently when the unexpected or never-before-encountered situation is encountered. I think the buzzphrase is training for resilience.
