I really don't even know why whether the cg matters or not is a debate anymore. As far as the USBC is concerned it does matter and, whether this is true or not, their acknowledgement that it matters in turn makes it matter. By saying that the cg has an effect on ball motion and creating regulations concerning side weight, they have essentially forced bowlers to use weight holes, which ironically have had a far more profound effect on ball motion that static weights ever could.
Kicking the cg out does matter from the perspective that it forces the bowler to use a weight hole which, can safely be said to effect ball reaction. Which can be seen in a very nice and instructive manner by viewing Brunsnick's weight hole video.
