Did they lose their mind or do they just want to leave us as fast a possible?

Nobody at this point wants to reduce the power down time in order to leave faster. 13 weeks is more than fast enough for anyone who wants to leave to have already long since powered down and left. Furthermore any proposal being discussed now would take more than 13 weeks to get implemented and deployed, realistically. So even someone who wants to leave and hasn't, can't still leave long before any proposal would take effect.

Whatever you think of the proposal, that's certainly not the motivation.
