Fair point, and the way you've put it is exactly the risk. If the author who lost the race can confirm a split on their own, they've decided the outcome for someone who never got asked. My direction is that a split isn't a special case at all. If the second author believes both decisions should stand, they don't override the original. They replace the decision that's currently standing with a new one that carries both, each scoped to its scope. That keeps the chain a straight line, it's recorded under the name of the person who did it, and the author of the decision that got replaced hears about it the same way they'd hear about any replacement. If they disagree, they replace it again and say why. The product I maintain will notify the original author in the future. So nobody gets to quietly relabel a replacement as a fork. Every step is a replacement someone signed, and the last word belongs to whoever is willing to put their name on the next one.
