Please attach pictures or names of the shops doing this work. Sounds like a lot of trouble to be pulling bearings after only 5k. Sounds like bullshit to me actually.
A highly reputable engine builder who I trust does not believe there is a tolerance issue.

I can assure you it's not and I'm not trying to push any agenda or anything.
No need to be defensive. I have no doubt that there are some cars that did quite well with them. I even know of a 180K mile S85 on the original set of BMW bearings that is still driving. Just putting out what I know.
Also, the bearings were pulled early as a part of an experiment.
