“A big change used to mean one giant PR nobody wanted to review. Now it’s a stack of small ones reviewers can actually follow, and the whole stack merges in one shot.”
Graphite built an entire company on this gap, and Gerrit shipped it in 2008. GitHub is arriving late and calling it new. The feature is genuinely useful, but note what it admits: the giant unreviewable PR was a workflow GitHub’s own design produced and left in place for fifteen years.
