Thanks for the link and recommendation. I'll try to add a manual WPT for this feature following the example of the other web app tests. Is this a blocking issue?

In the past it looks like manual WPTs have been added for certain PWA features in https://github.com/web-platform-tests/wpt/tree/master/appmanifest. Have you given any thought to adding any of that type of coverage for this? -- Dan On Wednesday, May 28, 2025 at 3:51:12 PM UTC-7 sligh...@chromium.org<mailto:sligh...@chromium.org> wrote: I'm recused from this one, but grateful and happy to see it moving forward.

Example usage: { "name": "Example", "display": "standalone", "start_url": "/index.html", "scope_extensions": [ {"type" : "origin", "origin" : "https://example.com<https://example.com/>"} ] } This allows sites that control multiple subdomains and top level domains to be presented as a single web app. Requires listed origins to confirm association with the web app using a .well-known/web-app-origin-association configuration file. { "https://sample-app.com/": { "scope": "/" } } Blink component UI>Browser>WebAppInstalls<https://issues.chromium.org/issues?q=customfield1222907:%22UI%3EBrowser%3EWebAppInstalls%22> TAG review https://github.com/w3ctag/design-reviews/issues/875 TAG review status Issues addressed Origin Trial Name Web App Scope Extensions Chromium Trial Name WebAppScopeExtensions Origin Trial documentation link https://github.com/WICG/manifest-incubations/blob/gh-pages/scope_extensions-explainer.md WebFeature UseCounter name kWebAppManifestScopeExtensions Risks Interoperability and Compatibility Gecko: No signal (https://github.com/mozilla/standards-positions/issues/904) WebKit: No signal (https://github.com/WebKit/standards-positions/issues/265) Web developers: Positive https://github.com/WICG/manifest-incubations/issues/105 https://github.com/WICG/manifest-incubations/issues/46 Other signals: Ergonomics None.
