GitHub explains why making stacked pull requests a native feature is more than just linking PRs and merging them in order, and how it required changes to core merge architecture and legacy systems.

Overview

The clip discusses the engineering complexity behind shipping stacked pull requests as a first-class GitHub feature.

Why it sounds simple from the outside: link related pull requests and merge them sequentially.
What made it hard in practice: updating core GitHub systems to support the workflow reliably.
Key engineering theme: delivering the feature required rethinking legacy merge architectures rather than layering a small UI/workflow change on top.
