Rotating people through the root ("central" if you insist on camouflaging the hierarchy*) positions seems an excellent idea. The biggest problem with rotations in general is the existence of domains requiring large amounts of specific knowledge, but I don't think anyone is arguing that administrative positions are among them.
— We're taking turns to act as a sort of executive officer for the week
— Yes...
— But all the decisions of that officer have to be ratified at a special bi-weekly meeting
— Yes I see!
— By a simple majority, in the case of purely internal affairs
— Be quiet!
— But by a two-thirds majority, in the case of more major
— Be quiet! I order you to be quiet!
(I wonder how the Pythons themselves handled group decisions?)
