I don’t know what you hope to accomplish by repeatedly asserting that there are no checks and balances. The team has been very clear about this: they are subordinate to the RFC process. The community can use RFCs to hold them accountable and impose any checks and balances the community can get through the RFC process. If you have a specific proposal, make an RFC for it.
If you do make such an RFC, and if it is accepted, and the mod team for some reason refuses to abide by it, then it’s time to say oh no, there is no accountability. But the rules of the game seem pretty clear to me right now, with no evidence that they won’t be followed.
