This doesn't change the sport in any negative way that matters. In fact, in some ways the enforcement of it improves things. I hated how catchers would set up in front of the plate without the ball, or at least without having the ball in a position where they could tag the runner, blocking any possible avenue the runner had. That's just as dangerous for the runner to try to slide through all that equipment to have a chance at the plate they're supposed to have anyway. They have two options, slide into the equipment and risk injury, or bowl over the catcher and risk injury.
BTW, for the record I think they should make it a rule that players can not intentionally make contact with a fielder (such as at second) unless the fielder is blocking their path. (Ie, no going out of their way to get a piece of the fielder, especially after they're already technically out)
