Unfortunately the reality is that distros spend months certifying the base kernel for both application and security conformance. And many (most?) of the large system customers will only run this kernel. Even changing root startup options is considered invalidating the conformance testing. That means the kernel has to adapt to the resource needs of the system being serviced.
Ideally, linux shouldn't have any fixed resources. A system built to run on a massively parallel system should also boot and run on a smart phone (not well perhaps... ;-)
