Summary

This feature applies Private Network Access checks to web workers:
dedicated workers, shared workers and service workers. These checks apply
to all worker-specific fetches: - initial worker script fetch - fetch
within workers - service worker script update fetch

In this first step, we'd like to ship warnings in DevTools to M110 when the
above fetches happen.  Currently, 0.000319% of worker script fetches [1]
and 0.043019% of the fetches within workers [2] are private network
access.  We think we can drive the number further down if we show warnings
in DevTools. We're also looking into allowing same-origin or same-site
requests, as Titouan mentioned in this thread
https://groups.google.com/a/chromium.org/g/blink-dev/c/FlenxUPCDec/m/C9LuRoQQAwAJ

Risks


Interoperability and Compatibility



*Gecko*: Worth prototyping (
https://github.com/mozilla/standards-positions/issues/143)

*WebKit*: No signal

*Web developers*: No signals

*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?



Debuggability

TODO


Will this feature be supported on all six Blink platforms (Windows, Mac,
Linux, Chrome OS, Android, and Android WebView)?No

Not enabled by default on Android WebView due to the lack of support for
deprecation trials.


Is this feature fully tested by web-platform-tests

Anticipated spec changes

Open questions about a feature may be a source of future web compat or
interop issues. Please list open issues (e.g. links to known github issues
in the project for the feature specification) whose resolution may
introduce web compat/interop risk (e.g., changing to naming or structure of
the API in a non-backward-compatible way).
