These types of tricks are gimmicks and often don't necessarily create "great" scenes, and instead reduce morale, create resentment and may have a detriment on the whole production. Not to mention the victim of these is often women and often in sexually violent scenarios.

Actors, especially trained ones, already have a process - whether its Meisner, Method, Laban, M. Chekov, etc to deal with stakes, emotion, vulnerability etc and it would behoove directors to at least partially understand that more than trying to invent their own on the hoof.

We don't hit a Foley artist with a metal bar to make them understand how to make the sound better, we don't stab the fight choreographer to make them understand knives better, we don't shoot the LX tech into the sun to understand the difference between INT and EXT, why do it to actors?
