Ok. If we are going to have those two forms, it means:

- grunt task will have to process the manifests (by removing the `_` from `rawManifests`);
- we'll call manifests the invalid (full merged) manifests, which is only useful for download builder;

If we expose one only option (raw format), it will mean the same for the grunt task (it will have to process it anyway), and we move the merge logic (which is only useful for db ) to db.

What do you think if we only export the raw manifests then?
