Yeah I think players and ittf don't want change. You can cheat a little and punishment only comes if you are going really overboard with it.This is what I mean when I say players don't really want to change the culture. They can fix some of this by actually making some of these things illegal and adjusting their body orientation a bit. However history and tradition and refusing to retain their serves are still king
If you want to regulate it make the rule that at contact no other body part can be closer to the net than ball and bat, I.e you have to hit in front of the body and not besides it.
That would basically mean you have to BH serve (although you could do it awkwardly with the forehand too but that wouldn't make much sense).
