Why? Find a flaw.

My main objection is with the fact that you describe it as THE BIGGEST CHANGE, which makes it look like a very disruptive thing, when it is in fact a change designed specifically to not affect uninterested Bitcoin users at all and introduce almost zero overhead and complexity.
I mean, if that change doesn't affect me as user, what incentive I would have to vote that fork positively? Seems weird
The other thing is forks involve enormous political complexity, so you can't say in the practice that this change isn't complex. If it requires a fork, it will always be complex.
