While concerns regarding concentrated loads on a unibody is valid, I think this is one area where we should put out faith in OEM engineers. I doubt they'd release a hitch rating without considering all static and dynamic forces acting on the hitch.
For me the question isn't whether something will break or not. I agree, engineers will take care of that. My issue is in handling of the load. How much body and frame flexing? I prefer live axles and a stiff frame over independent suspension and unibody. In vehicles I've towed with I see a big difference in how they handle the load.
