There's an interesting line of thought that a fragmented and diverse set of technologies and policies is more robust than a consolidated 'council'. You might be able to mess up any given district - but if you corrupt the council then you straight up win.

This makes a bit less sense when you look at how it ends up that a very few districts end up deciding the race - but I think the idea itself is sound. Those battlegrounds will shift, likely more rapidly than endemic corruption can take hold.
