-Cue flame war over hub-centric vs. lug-centric-
I'm sure for most people's DDs it doesn't matter if their wheels are lug centric. From an engineering perspective, though, it makes a lot more sense to put that load on the bigger hub rather than put an increased cyclic stress on the significantly smaller lug nuts.
