[css-fonts] Remove font-feature-settings and font-variation-settings descriptors?

At this point we don't implement other descriptors in @font-face, such as font-feature-settings and font-variation-settings - @litherum, do you suggest to keep those and only remove font-variant?

font-variant was removed per WG resolution; this issue is to track whether to also remove font-feature-settings and font-variation-settings descriptors.

There are currently no tests for either, so I plan first to make a couple of WPT tests and then discuss implementer interest in these descriptors.

We support the font-feature-settings descriptor but not the font-variation-settings descriptor.

Don't we need font-variation-settings for custom axes?

Webkit and Gecko implement font-feature-settings

Looks like Chromium, Gecko and WebKit implement font-variation-settings

Based on the WPT results, suggest closing this issue with no change. There are 2+ implementations in browsers of these descriptors

(Could do with more tests, but at least we do have tests for both)

Don't we need to distinguish the function of font-variation-settings as a @font-face descriptor and a style property? IMO that's the core of this issue. Which WPT tests demonstrate that Blink and WebKit respect font-variation-settings as a descriptor? Blink implements font-feature-settings and font-variation-settings as style rules / properties. (I'd have to double check but) I don't think we implement it as a descriptor.

IIUC the intention of the use of font-variation-settings as a descriptor is to set something similar to a "default" value for this font face - so no extra style rule needs to be placed to instantiate the font at a specific coordinate in the variation space.

Ah, indeed. Ignore what I said earlier about WPT.
