Finch feature name

Requires code in //chrome?

False

Feature is available on Web Platform Baseline

Ship it

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).

The color-adjust shorthand is defined in the spec but marked as deprecated. For that reason, this intent does *not* ship that shorthand.

Is there really no Finch flag here, or is it just not recorded in the email? I'd recommend we have a flag as a risk mitigation.

Thanks,

Vlad
