I need to do something across all our defconfigs at some point, but I want
to be done more thoroughly:

For any option or group of options that disappears from a defconfig file, I
want to see one patch (ideally across all such files) that explains why
the option that used to be intentionally enable is no longer there. If it
got renamed or replaced by something else, that should be set instead.
If there is a new dependency, we may need to enable that in addition
to the old option, rather than dropping it silently.

For options that just move around in the file, I would group them in
a final cleanup patch.
