The double threshold mecanism ensure that a BIP have approval before rolling out.
However, currently before any voting take place, we can get in the mess of today about which BIP to plan for activation.
Why not having a way for miners to informally vote to several BIP at the same times (where core devs would filter demands of proposal based on the quality of BIP, and of its PR), then when the vote is done, plan the switch at a specific date "manually" (without double threshold), or with threshold activation.
We can :
Informal Vote (no double treshold activation) => Plan (new bitcoin release including the bip) => Vote (threshold activation)
This is my understanding that most miners would agree to a kick the can solution overnight, without discarding another potential long term solution.
However, they have no way to express such interest right now, so we get this noisy environment where everybody try to talk louder to get heard.
