Like I mentioned in review of v1, moving *just* enums from one module into
another is rarely a desirable change without any additional context. So this
patch should be combined with changes that actually require such a code
movement, either in this series or in a separate one (doesn't matter), but in
its current shape this patch is a little out of place in this series.
