They are designed to increase scoring, but I am not sure at this point anyone can legitimately say that is what is going on.
The problem that I have and always have had is that officials don't call the rulebook and each crew is different.
Here has been my issues so far this season: How can you call all the touch fouls, but let all the body contact go in the lane? Not all crews do this, but tonight was an example of how the officials still don't know what they are calling.
It is too inconsistent at this point, but why would anyone expect anything else, officiating has been poor for the better part of the last decade. It is a travesty to try and change rules to aid in the deficiencies of the officials. What makes it worse is that now it is making the officials the focal point of the game. Then adding to that, they officials are affecting the flow of the game and at critical points the ending of a game.
Just call the game as intended and rule changes like this wouldn't need to happen.
