Allow me to understand: is it a blockchain fork you want to prevent? (not Core vs XT, but BIP vs BIP?) Your idea is that the miners will have accurate information about the will of the users, and choose that option unanimously?
Yes, this would be the most profitable solution for all. On the whole I want to prevent the split of the community.
This is the bitcoin way for consensus. Anything else is just speculation.
Miners role is to prevent double spending, but not to decide whether pull requests should be accepted.
