Requires token based diffs for what? I think the whole idea of a graph that puts automated code measurement against a dev name is misguided. It's very noisy and any actionable information you may want to get from it should be clear from other sources. Code is there, because that's the tool used. Who wrote how much code on what day is non-actionable.
If you can grade code quality, do it pre-commit/pre-merge. Why allow bad code in the first place?
