Specification
TBD
Summary
Adds a "scope_extensions" app manifest member that enables web apps to extend their scope to other origins.
Example usage:
{
"id": "",
"name": "Example",
"display": "standalone",
"start_url": "/index.html",
"scope_extensions": [
{"origin": https://*.example.com},
{"origin": https://example.co.uk},
{"origin": https://*.example.co.uk}
]
}
This allows sites that control multiple subdomains and top level domains to behave as one contiguous web app.
Requires listed origins to confirm association with the web app using a .well-known/web-app-origin-association configuration file.
{
"web_apps" : [
{"web_app_identity": https://sample-app.com/}
]
}

Other signals:
WebView application risks
Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?
No.
Goals for experimentation
Learn about the experience of web app developers and how this API fulfills their needs.
Ongoing technical constraints
None.
Debuggability
Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?
No. This feature will not be supported on Android platforms as web apps on Android have a different implementation of identity.
Is this feature fully tested by web-platform-tests?
No.
