Bitcoin is a mathematical money system and voting isn't the way mathematicians achieve consensus.
There must be a better way to do this, like figuring out the
definition of Bitcoin first and then seeing what proposals fit the idea of Bitcoin moving forward better than others.
Who are mathematicians? Why do you think they should decide which of proposals fit the idea?
Without a vote how do you know there is consensus achieved?
Mathematicians are the ones who dig for the truth.
Once they reach that layer, they simply know they are there.
Theoretically you can achieve consensus all on your own.
But the challenge then becomes to let others see it as well.
I'm not saying that Bitcoin can't step out of its way as a result of popular vote.
It sure can, but the true path of the original Bitcoin isn't ambiguous.
