The text discusses the challenges developers face with traditional GitHub pull request (PR) workflows, highlighting how large and complex PRs can slow down review cycles, introduce bugs, and create bottlenecks in the development process. It introduces "stacking" as a solution, a method that breaks down large features into small, manageable, and interdependent PRs that streamline the review process, enhance code quality, and increase development speed. By using tools like Graphite, which automates the stacking workflow, developers can maintain continuous integration with the main branch, reduce technical debt, and minimize downtime caused by monolithic changes. Stacking facilitates a more efficient and productive development environment by enabling parallelized development and review, resulting in more reliable and timely project delivery.
