I don't agree: the point of EXPERT is to show _everything_, which
means DEBUG_KERNEL should be selected to show those options as well. I
think this is fine as-is. What is the problem you want to solve?

I think of it as low (nothing selected) medium (DEBUG_KERNEL) and high
(EXPERT and DEBUG_KERNEL). So EXPERT enables DEBUG_KERNEL too.
