So it may still come down to just lubrication.
Chain saw bar oil has ingredients in it that keep the oil on the chain, and not flying off at high RPMs. On our Porsche motors, we want the opposite.
One thing I have thought about. How many ball bearings do you see fail in transmissions, wheel bearings, motor cycle engines, the way IMS bearing fail . While they may wear to a point of needing replacement, I don't recall seeing the complete failures in these bearings that the IMS bearing seems to exhibit. When the bearings are bathed in grease or oil, complete or catastrophic failures are very rare.

But Pedro's video shows centrifugal force throwing oil AWAY from the IMSB area? Not that I agree with that, but your hypothesis states the opposite.
The M96 bearings LOVE RPM because it helps unload them, the M97 bearings hate it because the components spin too fast. M96 bearings fail on the street, M97 bearings fail on the track and seldom on the street, very seldom. Load is the evil constant.
