This comprehensive guide, likely from Chromium's internal documentation, outlines the structured feature launch processfor new HTML/CSS functionalities within the Blink team. It details a multi-stage "Intent" lifecycle, from initial ideation and prototyping behind flags through developer trials and optional origin trials for real-world feedback. The document emphasizes the importance of community engagement, specifications, testing, and crucial API owner approvals (LGTMs) at key milestones like Intent to Experiment (1 LGTM) and Intent to Ship (3 LGTMs) to ensure interoperability, web compatibility, and user benefit before a feature is fully enabled in Chrome. The process also highlights the use of tools like ChromeStatus for tracking and UseCounters for measuring adoption, illustrating the rigorous approach to responsible web platform evolution.
