Hello.

Feature Policy is a powerful web platform tool that allows developers to control the behavior of APIs and features, similar to CSP. It helps manage third-party content by enabling or disabling functionalities like autoplay, geolocation, and sensor access within iframes, giving embedders more control over their page experience. Additionally, Feature Policy assists in maintaining performance budgets during development by flagging potential violations, such as excessive image downscaling, as demonstrated with the 'max-downscaling-image' policy used during Chrome Dev Summit. Developers can explore more about Feature Policy, code samples, and demos at featurepolicy.rocks, submit feedback at https://bit.ly/2B3gDEU, and learn about the Reporting API at https://bit.ly/rep-api.

I've been working on Web Intents, a project to simplify client-to-client service discovery and communication on the web using technologies like IFrames and SharedWorkers. It addresses the current issue of apps needing to integrate with third-party services, which restricts user choices. However, I recently discovered a similar project, Web Introducer, also by a Googler. It tackles the same problems with more in-depth security considerations. So, I'll be shifting my focus to contribute to Web Introducer. Web Intents remains a valuable example of using SharedWorkers and messaging effectively within web apps. More on Web Introducer and SharedWorkers coming soon!
