 Your existing deployment is unaffected after this change, and `seed-farmer` will continue to destroy as it previously did UNTIL the module you are looking to destroy has been sucessfully deployed with this version.  In other words, your modules WILL NOT benefit from the persisted bundle feature UNTIL they are deployed successfully with this new `seed-farmer` version.  In that regard, `seed-farmer` will continue to delete modules they way it always has (is backward compatible).
