*Subject:* [EXTERNAL] Re: [blink-dev] Intent to Ship: Support
font-feature-settings descriptor in @font-face rule
LGTM1, thank you for addressing this pain point for developers!
The scope of this intent is font-feature-settings, but now that
https://chromium-review.googlesource.com/c/chromium/src/+/6582382
<https://chromium-review.googlesource.com/c/chromium/src/+/6582382>
has been merged, do you want to ship support
for font-feature-settings and font-variation-settings together? I
think that would be great, but my LGTM is not conditional on it.
I also confirmed that the linked tests are failing on stable but
passing on experimental, so everything seems to be in good order!

Specification
https://www.w3.org/TR/css-fonts-4/#font-rend-desc
<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.

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).
