As a guy who was constantly shooting and pushing the action, I love the first point about takedowns. If you're on your butt and your opponent has both legs wrapped up, you are taken down. If you're hanging on to a lock around the waist, or in the crotch at this point, you're looking for a stalemate. Which also means that you're stalling. If you're not actively looking to improve your position or score then you're stalling.
I also like that no riding time without BP idea. It would be simple to adopt and wouldn't require putting any more judgement calls in the hands of officials.
