Not only is it faster, but it works, and no script will change
anything to that, because it's inside the kernel that the problem

The old 'it touches too much kernel code' refrain is not true anymore,
as many necessary changes have been incorporated into the vanilla
kernel over time.

Ubuntu already incorporates many things in its kernel that are not in
vanilla ones, so I think this cannot be an argument not to accept

WRT checking the code, how about involving Dagobah?

In a world without walls and fences, who needs Windows and Gates?
