12 Bolt Aluminum Cover - Added strength or no?

Hey guys. This is for all you Chevy truck 12 bolt experts out there. Do you believe that a cover such as this adds any real overall strength to a 12 bolt? From the vendor:

Rim Automotive wheel system Bicycle part Silver Watch

"Made from 356-T6 cast aluminum, these girdles incorporate a reinforced crossbar. The crossbar houses the load bolts that apply pressure to the bearing caps. This feature, along with the thick casting, prevents bearing cap deflection under severe loads. Which in turn greatly reduces or eliminates (in most cases) bearing cap fatigue and failure. "

Thats a nice 356-T6 casting. Its well machined and the 2 examples I saw were very well done (We design and finish machine aluminum castings at Auto Gear). As far as the bearing cap pre-load bolts? No idea if thats good bad or indifferent. I suppose I'd say Buy it because its a lot more leak resistant than a stamped cover; and she pretty. Is it going to save your rear if you're locked in a race? 12 bolts are plenty strong; how much overhead does your ride need?
ETA: I agree with Joe's assessment above as well.
