I am also pretty interested in 2 (ex-post giving). In 2015, there was impactpurchase.org. I got in contact with them about it, and the major updates Paul reported were a) being willing to buy partial contributions (not just for people who were claiming full responsibility for things) and b) more focused on what’s being funded (like for example, only asking for people to submit claims on blog posts and articles).
I realise that things like impactpurchase is possibly framed in terms of a slightly divergent reason for 2 (it seems more focused on changing the incentive landscape, whereas the posts above include thinking about whether giving slack to people with track records will lead those people to be counterfactually more effective in future).
