there's several things happening in the proposal, not just the conflict score.
The proposal was needed because of the change to the pack types, everything else probably could've be done by the team. But why not include the full picture so that everyone can see how its all connected, that way they don't object to the changes after they are released?
Keep in mind that there were many people on both sides of these Conflicts issues, and some were vehemently upset with some parts of it. To be fair to everyone, and to get a good gauge of sentiment, its better to include all the changes for that full picture.
