 Hi @ webkit-dev, hi Myles,

we'd like to know your opinion on the extended supports(<font-technology>) syntax of the @font-face src: descriptor.

Specification or proposal URL: https://drafts.csswg.org/css-fonts-4/#font-face-src-parsing, in particular the [ format(<font-format> [supports <font-technology>#]?)]? part of the spec. The changes have originally been approved / developed in the CSS WG process already. As we're considering shipping this feature, we'd like to know if Apple is considering implementing support as well.

CSS WG Resolution for issue #633 initially adding format() and supports() syntax CSS WG change in issue #6340 to clarify parsing rules for supports syntax

Is this something you're considering developing / shipping in WebKit? As Myles has been an active contributor in the proposal in issue #633, I am hoping we have your support on this matter.

Positive signal.

Thanks in advance,

Dominik
