Hello.

Jason did an amazing talk about a little-known but new area of the web platform ‘Feature Policy’. Feature Policy is a new primitive which allows developers to selectively enable, disable, and modify the behaviour of certain APIs and features in the browser. It’s like CSP, but for features & APIs! Teams can use new tools like Feature Policy and the Reporting API to catch errors before they grow out of control, ensure site performance stays high, keep code quality healthy, and help avoid the web’s biggest footguns.
