Is this worth +500 new lines? What will we change given this information?

It's not strictly necessary, but gives a good overview how the kernel size changes and which configs are changing in the PR.

[adeebshihadeh]

Does the kernel size change much though? In my experience, I've never worried its size is growing or changing much, which is very different than my experience working on the userspace.

I dont expect it to change much. Let me close this PR for now in the interest of codebase maintainability.
