I mainly wanted to avoid having some user-space developers think "but
I know better than the kernel!". I don't want to document that the
kernel will exclusively change the mode list because of quirks, then
figuring out that we need to fix-up another EDID field for other
reasons, and end up with complains.

I added an intentionally short explanation in v2.
