This thought may be academic now that the majority of P6 cars on the road will be weekend cruisers, but the better the crankcase ventilation the longer the oil and engine internals will stay clean and the longer you will be able to go between changes.
I only have 3000 miles on the insurance currently, so my oil gets changed annually anyway. But a 10,000 mile a year car would need two or three changes and good ventilation, converting to road draft and having no positive ventilation will not help cleanliness.
