I certainly would be interested in seeing such a system go into place—I think it would probably be beneficial—the main issue is just whether something like that is likely to happen. For example, it might be quite difficult to establish agreement between Charity Evaluator and GiveWell when it comes to the benefits of certain charities. Additionally, there may be a bit of survivor bias when it comes to organizations that have worked like FIDE, although I still think the main issue is 1) the analysis/measurement of effectiveness is difficult (requiring lots of studies vs. simply measuring album downloads/streams); and 2) the determination of effectiveness may not be widely agreed upon. That’s not to say it shouldn’t be tried, but I think that might contribute to limiting the effectiveness relative to the examples you cite.
