This is necessary so that the shadow version can actually keep track of what provider is used for what. Before, providers for different alises were just initialized but the factory had no idea. Arguably this is fine but when trying to build a shadow graph this presents challenges. With these changes, we now pass an opaque "uid" through that is used to keep track of the providers and what real maps to what shadow.
