This isn’t really necessary, John. A proposal must be fair, technically sound, and have support of the community in order to be adopted. Just because it is technically sound and/or fair does not mean that the community must support it. People are free to reject a policy for any reason, though I admit a bias in favor of at least some rationale for rejection.
