I agree with you that there is a need to define structures to address “governance” such as moderation issues. For example, it would be useful to have a way to fight the idea that “blocking stuff” is a silver bullet.
However, I don’t think this can be the place. There are already more discussions happening here than I can process. Adding another complicated topic to the Discourse will make SocialHub less usable. I also think that the technical and social problems of the FediVerse currently don’t have a lot of overlap.
There is just too much ground work left, before one can start on the hard stuff.
