Positive displacement oil pumps don't care how small or big the oil filter is.
Physics doesn't work like that. The pump is still limited to the amount it can flow per rpm in simple volume. If the pump simply can't move enough oil, you run into problems.
VW had to spin up an update for the oil pump on the 06B block engines. The stock pumps would wear a little, and if you had say an oil cooler, the engine would starve for oil at lower RPMs.
Just because a positive displacement pump will move say 5ccs of at 1 rpm at 100psi or what ever the bypass setting is, doesn't mean anything if the system needs 7cc of flow for every revolution. This presents as oil starvation at bearing surfaces usually, where flow is directly tied to pressure.
