Lots of funding is implicitly retrospective in the sense that what you’ve done historically is a big input into whether individuals and groups get funding. Yet, because most funding mixes several factors including past work, anticipated future work, reputation, etc. I think there may be an open opportunity here.
I’d be particularly excited to see funding for projects that have already occurred where it is clear that the success or failure of the past project is all that is being considered. This might encourage more unconventional or initially hard-to-assess projects and would provide a more concrete signal about which projects actually succeeded historically.
