These pumps were under constant high rpm stress and never saw a single failure.

The one piece plate is not designed to fix bearing races that are spinning in the case. They are designed to stop if from happening in the first place. It wasn't a new idea, and was something they did on the 930 and 931 gearboxes from day one. Once someone spends the money properly machining and fixing the case, it's a nice finishing touch.
Don't know how many loctite'd races I've seen spin over the years. Maybe it's an acceptable fix on a street car driven once in a while, but if you flog your car or track it, you'll be back in there sooner rather than later.
