@nikomatsakis Having somebody curate the discussion is a noble idea, but I suspect that enforcement of that policy would be hard. But maybe the difficulty is a good lever for making under-motivated RFCs go away more quickly. If nobody is willing to maintain the summary then it’s clearly not important enough, and a bot can auto-close it.
I also though think that the summary of the discussion belongs in the RFC. When I come to an RFC PR with hundreds of comments I expect to be able to read the RFC to understand the state of the proposal. The RFC should contain an up-to-date consensus design, and all the dissent should be recognized in the alternatives and open questions sections.
