Apologies, I had the wrong link in the spec link section. I've updated
it, but it should be https://github.com/gpuweb/gpuweb/pull/5431.

*Specification*
https://github.com/gpuweb/cts/pull/4516
*Summary*
Functionality added to the WebGPU spec after its first shipment in
a browser. Adds a new scope to the uniformity analysis and changes
which parts of the language are checked in each to allow subgroup
functionality to be considered uniform in more cases.
*Blink component*
Blink>WebGPU
<https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EWebGPU%22>
*Web Feature ID*
webgpu <https://webstatus.dev/features/webgpu>
*Motivation*
This feature allows subgroup functionality to be considered
uniform in more cases representing better quality-of-life for
developers and less likelihood of disabling uniformity checks
altogether.

*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*
/No information provided/
*Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?*
Yes
All platforms will eventually have support. Will immediately be
available on Android, Android WebView, ChromeOS, Mac, and Windows,
since those platforms already support WebGPU. WebGPU will also
start shipping on Linux in M145 on some devices, so this feature
will become available when WebGPU does.
*Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?*
Yes
WebGPU conformance tests were added in

*Estimated milestones*

Shipping on WebView 145
*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).
