A tool indeed, but not a magic wand. Whether it is a good tool for policy-making is not entirely up to the user, the tool per se may be defected for that purpose.
Of course it's not a magic wand, nothing is. Even if a tool is defected, a good user can still produce good results. We work with defected tools all the time. There is no such thing as a perfect tool when it comes to dealing with $ of many people.
