to my understanding, the governer (or whatever SPOF) is again yet
another problem. I agree that it has the same impact in both designs.

when you have as less as it gets in kernel space, however, you are
exposed to less vulnerabilities inherent to the (governed) code (running
user space), which the SPOF is not in control of.
