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.
so you're saying you think core will not/should not, add in the code required to allow miners to activate a HF with >75% hashing power.
Correct.
And even if we did, it would be futile, since neither devs nor miners can force users to adopt it.
It is literally technically impossible for miners to activate a HF period.
hashing power has a strong incentive to align itself with the will of the userbase.
your right miner cannot HF somthing the user base will not adopt
but IMO you're wrong in thinking the user base will not adopt a 2MB HF should if it achieve >75% hashing power and get activated.
it's really sad to hear you will not code in that 2MB HF.
