Seems you did lots of tests to find optimal settings for a given base
policy.

What is missing in the kernel UAPI so userspace could do these settings
on its own, without adding this policy stuff to the kernel?

It seems strange to me to add such policies to the kernel.
Addmittingly, documentation of some settings is non-existent and one needs
various different tools to set this (sysctl, procfs, sysfs, ethtool, etc).

But all of these details could be hidden from user.
Have you looked at tuna for instance?
