And by relevant, I mean at least two VQ37VHR's with lightweight pulleys and oil pump failures at 'Normal' RPMs (ie, not revved to 9K where they blew up... revved to 7500-8000 where they blew up).

It's just my opinion. Connecting the dots more or less.
From some things that I have read. Seen first hand. Experienced myself. Like breaking a forged crankshaft in a Chevy LT1 I had some years ago. Having some friends who broke the oil pumps on their Hemi's.
