On the other hand, it would be really neat to see a system that tried to bring it back. I imagine a character sheet with hit locations and target numbers on them replacing AC. Different parts would require different rolls to hit, and you could choose to hit any spot lower than what your to hit roll was.
It'd be good for a system that was designed to be pretty gritty, because actual injuries are only worth tracking in such a system. But it would be nice to see a modern game at least attempt it again. It kind of comes down to how detailed you want to track damage. Hit locations work well in Battletech, because the game revolves around single encounters, so it is worth it to manage hit locations in great detail. If you want to have more fights, you want to start abstracting things a little more.
