Without knowing the specifics: I doubt a governance structure will produce good leadership. I've seen Rust people place their hopes in abstract, convoluted processes, and they've failed repeatedly.

Rather, I see the problem as character. The chosen leader(s) need the internal, personal qualities necessary for getting volunteers to cooperate well. External structure won't save the project if leaders lack character, it will just slow the damage they can wrought.

Relatedly, I was uncharitable before in emphasizing the weakness of Nix's leader. I think we all lack the moral (apolitical) education necessary for just leadership.
