Deleted documents specifically allow for a body to be set in the deleted revision. The intention for this is to have a "who deleted this" type of meta data for the doc. Some client libraries delete docs by grabbing the current object blob, adding a '"_deleted": true' member, and then sending it back which inadvertently (in most cases) keeps the last doc body around after compaction.
