Risks
Interoperability and Compatibility
This feature has not yet been implemented in any browser. It has been
approved by the GPU for the Web Community Group, with representatives
from Chrome, Firefox, and Safari. See
https://github.com/gpuweb/gpuweb/pull/5147 with approval from
representatives of Firefox, Chrome, and Safari as well as links to
minutes.
/Gecko/: Positive (https://github.com/gpuweb/gpuweb/pull/5147) This is
already implemented in Firefox but WebGPU itself is still behind a flag.
/WebKit/: In development (https://github.com/gpuweb/gpuweb/pull/5147)
This is already implemented in Safari but WebGPU itself is still
behind a flag.
/Web developers/: No 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?
None
Debuggability
None
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
No
All platforms will eventually have support. Will immediately be
available on Android, Android WebView, ChromeOS, Mac, and Windows,
since those platforms already support WebGPU. Linux is planned to have
WebGPU support in the future, 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/WGSL have a conformance test suite
(https://github.com/gpuweb/cts) that is regularly pulled into Chromium
and part of the testing of Dawn/Tint in Chromium. While the CTS can be
embedded in WPT, the WebGPU team opted to keep it separate in Chromium
testing to use a customized harness for robustness and performance.
All the tests about this feature in WebGPU CTS can be found through
the below link: https://github.com/gpuweb/cts/pull/4228

Rollout plan
Will ship enabled for all users
Requires code in //chrome?
False
Tracking bug
https://issues.chromium.org/issues/418025721
Availability expectation
Feature is available on Web Platform Baseline within 4 months of
launch in Chrome. Safari, Firefox, and Chrome have all implemented
this feature. Safari and Firefox have not yet shipped WebGPU to their
stable versions but appear close to shipping. Chrome's support is
currently behind a flag.
Adoption expectation
Feature is already considered best practice. Chrome needs to ship so
that developers can start following best practices. Currently they
require hacky and non-perfect workarounds.
Adoption plan
Major WebGPU libraries like three.js will adopt this feature soon
after it's available in Chrome.
Non-OSS dependencies
Does the feature depend on any code or APIs outside the Chromium open
source repository and its open-source dependencies to function?
None
Estimated milestones
Shipping on desktop 139
DevTrial on desktop 136
Shipping on Android 139
DevTrial on Android 136
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).
