Low oil pressure after shim

So when a cam bearing spins it will increase it's diameter and/or shift forwards or backwards. This allows oil that would normally be under pressure between the cam and rockers to be released into the overhead, so much that the oil pump can't keep up, lowering the general oil pressure.

Wonder why the bearing isn’t designed with cut almost the whole length (diameter) to prevent oil loss to the cam in case of bearing slippage.
