All I want to know is if the core devs will allow miners to "vote" for the 2MB HF activation.
Definitely not. Miners do not decide hardforks, much less vote on them.
so much for "Luke is focused on fulfilling the promise"

The HK roundtable included agreement on this point, that miners do not decide hardforks. It doesn't contradict it in any way.
Even if it wasn't part of the document, this inability of miners to decide hardforks is an aspect
inherent in the nature of hardforks, not something I nor anyone else has decided.
