Is fireplace going to use this? Or will be be searched at all via the consumer pages? If not, we can skip this until we need it.

I know the reviewer tools will use this field but this won't work for them... they need `is_privileged` attached to the latest version, not the current version. There's a bug floating around to add some extra data for reviewers. There's also a bug or idea to move the reviewer tools to elasticsearch and avoid some of the ugly queries.
