The example in the description is a bit confusing found here: https://chromestatus.com/feature/5170361717489664
Before, a permissions policy might need to look like: ``` permissions-policy: ch-ua-platform-version=(self "https://foo.com"; " https://cdn1.foo.com"; "https://cdn2.foo.com";) ``` With this feature, it could look like: permissions-policy: ``` ch-ua-platform-version=(self "https://foo.com"; "https://*.foo.com";) ``` One would think why not just write: `ch-ua-platform-version=(self " https://*.foo.com";)` instead. As you're used `foo.com` twice! ---- Would it not be better to use `foo.com` and `example.com` instead e.g. Before, a permissions policy might need to look like: ``` permissions-policy: ch-ua-platform-version=(self "https://example.com <https://foo.com/>" "https://cdn1.foo.com"; "https://cdn2.foo.com";) ``` With this feature, it could look like: permissions-policy: ``` ch-ua-platform-version=(self "https://example.com <https://foo.com/>" " https://*.foo.com";) ``` Which would make more sense.
