This does not show up on the API Owner dashboard in Chromestatus so
maybe you have missed pushing it there? There are some other reviews
that should be started there at the same time.

The review for the font-variation-settings CL
<https://chromium-review.googlesource.com/c/chromium/src/+/6582382><https://chromium-review.googlesource.com/c/chromium/src/+/6582382>is
currently underway. Due to notable differences in implementation and
interoperability, I have created a separate Chrome status entry for
it. If necessary, we can wait until the variation settings CL is merged.
Thank you,

font-feature-settings descriptor in @font-face rule
You don't often get email from yio...@gmail.com. Learn why this is
important <https://aka.ms/LearnAboutSenderIdentification>
Thanks for your work, this is a feature that Blink has been lacking
for a long time, very much looking forward to it!
Are you planning to ship the `font-variation-settings` together? We
hope they can be released together.

Specification
https://www.w3.org/TR/css-fonts-4/#font-rend-desc
Summary
As CSS allows fine control over font features using
'font-feature-settings' at the element level, Chromium-based
browsers currently lack support for these properties within
'@font-face' declarations.
This feature supports the string-based syntax for
font-feature-settings as defined in CSS Fonts Level 4. Invalid or
unrecognized feature tags will be ignored per specification. No
binary or non-standard forms are supported.
As OpenType fonts become more widely adopted, this enhancement
will improve typographic control, reduce redundancy, and support a
more scalable, modern approach to web design.

<https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EFonts%22>
Motivation
CSS already provides a 'font-feature-settings' property for
controlling OpenType features at the element level. However,
Chromium does not currently support it within @font-face
declarations, unlike Firefox and Safari.
This limitation prevents developers from configuring font behavior
during font loading, forcing redundant declarations across
individual components or elements.
Supporting these descriptors in Chromium would let developers
define font behavior once—at the source—improving consistency,
reducing repetition, and making it easier to verify applied
settings through DevTools.
