Could you write a few sentences why this is a
useful addition?
Service Workers enable offline capabilities and
background processing for WebGPU. This means
graphics-intensive web applications or Chrome
Extensions can cache resources and perform
computations even when the user isn't actively
interacting with the page.
Shared Workers allow multiple tabs or extension
contexts to coordinate and share WebGPU resources.
This leads to smoother performance and more efficient
use of the user's graphics hardware.
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.
Indeed.
/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.
Agree ;)
/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?
Yes. WebGPU is supported on Android WebView as well.
Note that Shared Workers are not available on Android for
now. See https://issues.chromium.org/issues/40290702
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).
