I don't have an answer. But look at optimistic rollups with a typically 7 day fraud proof window. Current expectation is that in the face of a censorship attack, Ethereum could fix this and fork in that time span to recover. Requiring that an EIP needs "x week community consideration" seems wrong in this light.
I would love to have more of a community call in addition to ACDs, where members can give their inputs on their priorities. I think this is completely missing at the moment. But just "extending the timelines" is precisely not what we should do.
