Ayo GitHub Quietly Killed the Unreviewable Mega-PR

GitHub PR improvements are highly actionable for developers and directly relevant to SDLC.
GitHub quietly shipped native stacked pull request support, enabling developers to break large PRs into chains of smaller, dependent PRs without requiring CLI extensions or third-party tools. By simply setting the base branch of each PR to the previous branch in the chain (e.g., PR #11 targets the branch of PR #10, not main), GitHub automatically detects the stack and displays a 'Preview stack' banner with a progress badge. This addresses the long-standing problem of unreviewable mega-PRs by ensuring each PR in the stack only shows its own diff, making code reviews more effective for both humans and AI tools.
