This is exactly to insulate against these kinds of changes that this
doc patch exists in the first place and documents what things mean for
the kernel.

Kernel-wise I do not think we can be assume that changes such as these
could be implemented right away so there is no need to change the doc
at this stage.
For now the kernel doc is the reference and nothing else. So this
patch should NOT be changed IMHO at least not now.
Eventually this could happen in the future, but not out of order with
actual patches to update the code and tooling and certainly not now.
