Re: [csswg-drafts] [css-conditional-4] Feature detection for descriptors (#2463)

Just want to mention [my syntax suggestion from #5929](https://github.com/w3c/csswg-drafts/issues/5929#issuecomment-774475760) here:

```css
@supports (@page { size: 10cm; }) {
...
}
```

That would work like the existing parsing checks for properties and selectors, so no new logic here. It only requires to extend the syntax of `@supports` to take at-rules.
