[css-fonts-4] @font-feature-values { font-display }

[fantasai]

The Fonts 4 spec defines a font-display descriptor for @font-feature-values, which otherwise contains a bunch of at-rules. I can't find much discussion on it, so I wanted to know:

• Is this feature implemented anywhere?
• Do we need to keep it?

It seems like a really awkward place to put a font-display descriptor, @font-feature-values has nothing to do with loading fonts...

It is slightly awkward, but @font-feature-values is useful because it lets us associate things with @font-faces by name without having to modify the @font-face rules directly. In particular, this lets the author modify fonts pulled in from a font server like Google Fonts, for instance.

I believe it's implemented in Chrome, at least. @xiaochengh ?
