In 2025-11, delivered a major Namespace Review System overhaul in Azure/azure-sdk-tools, removing auto-approval and tightening review UI/logic to improve governance and reviewer efficiency. UI now hides the Request Review button when there are no related PRs and only shows it when API revisions exist and TypeSpec language is present. This reduces noise in the review queue and enforces intentional approvals.
