I remember there being a similar controversy when the latest Ace Attorney game got an M rating, and my opinion on that is pretty much the same here.
If the developer wants to include something that will make the game better and would result in an M rating, go for it. I'm not quite sure what that would be; maybe the game has some kind of destroyed residence with M rated gore to show how awful a certain group of bad guys are. With that said, I wouldn't suggest pursuing an M rating just for the sake of having it. Making a game violent just for violence's sake isn't a mark of good game design.
