I don't really have a dog in the fight, but I think the reality of this is that they want to encourage more action. I think that is good. However, rewarding someone for escaping a bad position that they shouldn't have allowed to happen in the first place is dumb. It might be more productive to award points to the person on top for working towards a sub while maintaining a top position. That would be similar to the riding time point or back points in wrestling. The decision to award those points would be at the discretion of the referee much like stalling. Points should be awarded for getting and maintaining a dominant position. The reward for escaping a bad position should be escaping the position.
