Who? Previously its me doing this work, i.e. keeping things in synch.
Actually it is expected that people doing the kernel work don't touch
tools/ wrt adding the copy, there is value in the warning, in looking at
what changed, to see if we should change tooling in some way beyond what
automation in merely making the copy can possibly do.

What has value is checking that the process of addressing the out of
sync warning doesn't break the build, to point to things that will need
human work to get it back to a buildable state.
