The Permissions-Policy HTTP header replaces the existing Feature-Policy header for controlling delegation of permissions and powerful features. The header uses a structured syntax, and allows sites to more tightly restrict which origins can be granted access to features.

Motivation

The Feature Policy API was recently renamed to "Permissions Policy", and the HTTP header has been renamed along with it. At the same time, the community has settled on a new syntax, based on Structured Field Values for HTTP.
