I don't think that's correct. Racing teams look to do this for removing friction, however using such bearings causes another issue: Survivability. This is an interesting read: Link

If it goes, what's to stop it from having the needle bearings clogging the oil passages? Where as compared to a regular journal bearing, if it fails, what's going to clog the oil passages?
