I believe the Dayan Lunhui is not competition legal because the design allows for new moves to be now possible, in violation of WCA regulation 3h):

Dayan modified Rubik's cube design to make the corners be freely rotated without any effort:

I really don't see any advantage in doing the new move and introducing parity cases into the world of 3x3x3 cubing, but I think WCA rules and regulations are very strict.
