Adds subgroup functionality to WebGPU. Subgroup operations perform SIMT operations to provide efficient communication and data sharing among groups of invocations. These operations can be used to accelerate applications by reducing memory overheads incurred by inter-invocation communication.
None
None. This feature exposes functionality for operations only within a single draw/dispatch. Data is contained within a single users run.
Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?
None
No special debugging is available for this feature as it resides solely on the GPU.
Does the feature depend on any code or APIs outside the Chromium open source repository and its open-source dependencies to function?

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).
Editorial changes only. Future features are likely to build on top of this extension.--

Also, can we please update the chromestatus entry title so
"WebGPU Subgroups experimentation" is less confusing on
