First, take the words from this RFC: "Anything merged into php-src is by definition a core part of PHP, regardless of the folder it goes into, or whether it has direct implications for our users. This is not a debatable fact: If it is distributed with PHP, it is core software". Does this mean that every merge into php-src requires vote? If not, why this sentence is here? Second, many significant internal improvements don't affect PHP behavior at all. Usually, they affect just few core developers and few third-party extensions maintainers. Should this really require super majority of all the voters? Or we can avoid voting, instead? We currently have voting rules, that more or less work. In case, anyone like to change them, it would be better to present new rules as a "DIFF" on top of existing ones (in the most possible compact, clear and formal way). Then we may vote on the whole "DIFF", or each change separately. I wouldn't vote for changes of rules without clear context. I hate politics, and wouldn't like to participate in this discussion :( Thanks.
