Thanks for the summary of the experiment results on Edge - sounds positive.
If this is purely a browser UI change, then we don't really need the
blink-dev process at all. However, if we're relying on concepts defined
in a CSSWG draft, and devs can change the outcome w/ some CSS (or maybe
here, the lack of CSS to result in non-`normal` computed value...) it
would be if there were interoperability in UI choices across browsers. I
don't necessarily think we should block on the outcome, but requesting
vendor positions could be useful.
(and Daniel, if you scroll down a bit - I did ask about TAG and browser
signals. :))

I agree that this lives in the borderland between user agent UI and a
web visible change so some shortcuts might be possible to motivate,
but you still need to click the the appropriate buttons in the
chromestatus tool.

Hello Mike,
Thank you for taking a look!
I am seeking consensus on how to approach the feature from a
standardization perspective. I think the feature can be considered a
browser UI change, which is why I haven't requested a TAG review or
signals from other engines. However, I am open to doing so if necessary.
I apologize for any confusion. We did the general experimentation in
Edge (not the "origin trials" as I mentioned in the email). Retention
reports were neutral, and we observed no regressions in scorecards.
Also, we have not received any negative user feedback thus far.
I am working on requesting reviews for my chromestatus entry. Thanks
for pointing this out!
Thanks,
Yaroslav

Hi there,
Would you mind requesting reviews for the various review gates in

Specification
https://www.w3.org/TR/css-color-adjust-1
Summary
Makes the browser use the user's preferred color scheme to
render the viewport scrollbars if the value of "page’s supported
color schemes" is 'normal' or not specified, and the computed
value of the color-scheme for the root element is 'normal'.
Viewport scrollbars can be considered to be outside the web
content. Therefore, the user agents should honor the user's
preferred color scheme when rendering viewport scrollbars if
page authors have not explicitly specified support for color
schemes.

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)?
Yes

Tracking bug

Measurement
Added a use counter UsedColorSchemeRootScrollbarsDark. The
counter tracks the number of users who have dark mode root
scrollbars due to the feature. Adoption in Edge Stable
population based on this metric is approximately 13%.
Availability expectation
Initially available in Chromium browsers.
Adoption expectation
This feature immediately affects specific use cases upon launch.
Adoption plan
This feature has been through origin trials on Edge. Other
browsers adopt this feature to fix specific use cases.
Any details or feedback you can share from the Origin Trial?
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?/
No.

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)./
