No, im more than happy to have additional outlets to what is already provided 
and im only listening to a higher rank that you only need 1 or 2 collectors...meanwhile have whatever you want for delievers 
Yes, I understand that having two more deliveries is a good thing, but why on earth wouldn't you want these to be 64mm, to give you the ability to use all 4 deliveries with 64mm hose if need be? There is no reason at all to have a 38mm delivery coming straight off the pump. Its all about that ability to adapt.
As for the number of collectors, do the math, its super simple. You need to be able to supply what ever you pumping out. The only reason I prefer to see the use of an even number, 2/4/6 collectors and delieveries is that for most pumping applications (Relay pumping, Boosting etc) you use an even number of deliveries and collectors. Having an odd number such as 3, is going to cause havoc if you need to boost a 4in system.
I understand that people see booster systems and the like as something unique and special, and something that they will never see or use, but if you have a booster in your area, you should have a truck that is capable of operating one. If you have a pump that can work at 3000lpm, then why not give it the ability to fully use its pumping capacity?
