Could you write a few sentences why this is a useful addition?
Specification
https://gpuweb.github.io/gpuweb/#navigator-gpu
Summary
Functionality added to the WebGPU spec after its first shipment in a
browser. ServiceWorker and SharedWorker support is added to WebGPU,
aligning with existing WebGL capabilities.

Risks
Interoperability and Compatibility
ServiceWorker and SharedWorker support have not yet been implemented
in any browser, but have been approved by the GPU for the Web
Community Group, with representatives from Chrome, Firefox, and
Safari. See minutes at
https://docs.google.com/document/d/15w7nsvqWwITA5yvCrsO3SEIEuZziXzj7YsrHN4Jd2uM/edit#heading=h.jbe7pg8ebd43
/Gecko/: No signal
(https://github.com/mozilla/standards-positions/issues/971)
Not officially a positive signal, but looking positive based on the
comments.
/WebKit/: No signal
(https://github.com/WebKit/standards-positions/issues/294#issuecomment-1877411933)
This is kind of an "N/A to positive", given it's WebGPU.
/Web developers/: Positive (https://github.com/gpuweb/gpuweb/issues/4197)
/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?
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, 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.
What about WebView? Do we ship support for WebGPU there?
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. PRs:

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).
