You misunderstood. It's not a middle ground between "can regulate" and "cannot regulate". That would indeed be idiotic. It's a middle ground between "must judge everything for yourself" and "someone else determines what you have access to". Someone else does the evaluation and tells you whether they think it's worthwhile, but you choose whose recommendations to listen to (or ignore, if you please).
