[Question] Is any EA organization using or considering using Buterin et al.’s mechanism for matching funds?

In Liberal Rad­i­cal­ism: A Flex­ible De­sign For Philan­thropic Match­ing Funds, Vi­talik Bu­terin, Zoë Hitzig and E. Glen Weyl pro­pose a mechanism for (near) op­ti­mal pro­vi­sion of pub­lic goods.

The pa­per is quite re­cent (De­cem­ber 2018). Con­sid­er­ing that the EA com­mu­nity may be vet­ting-con­strained, has any­one im­ple­mented or con­sid­ered im­ple­ment­ing the sug­gested mechanism?
