Re: [csswg-drafts] [css-conditional-5][css-nesting-1] Feature detection for nesting (#8399)

The CSS Working Group just discussed `[css-conditional-5][css-nesting-1] Feature detection for nesting`.

<details><summary>The full IRC log of that discussion</summary>
&lt;fantasai> astearns: We have a feature-detection story, question is how to detect browsers that support nesting vs don't support nesting?<br>
&lt;dbaron> astearns: Is that what's remaining in this issue?<br>
&lt;fantasai> TabAtkins: unsure... someone else should take this<br>
&lt;fantasai> SebastianZ: We need some way to migrate and have fallbacks for old browsers<br>
&lt;fantasai> SebastianZ: so the question is how to allow feature-detection, and at the same time do it so that all the browsers don't fail completely<br>
&lt;fantasai> SebastianZ: Of course they don't support nesting, but we need some way to handle that case<br>
&lt;fantasai> ???: We need more than just selector(&amp;)?<br>
&lt;dbaron> s/???/matthieu/<br>
&lt;astearns> s/???/matthieu/<br>
&lt;fantasai> SebastianZ: selector(&amp;) does work, but it focuses on style rules. Doesn't target whether other rules can be nested, or media rules, or something else<br>
&lt;fantasai> astearns: Given that we have not much time yet, does it make sense to continue the discussion of this upgrade strategy in this issue, or should there be a separate issue just on the path we want authors to take when they don't know whether the browsers supports nesting or not?<br>
&lt;fantasai> SebastianZ: I think there's an issue targetting the author experience... not sure which one it was<br>
&lt;fantasai> astearns: Since this feature is titled Feature Detection, should we close this issue and find or create an issue about the author experience?<br>
&lt;fantasai> SebastianZ: Hard to say<br>
&lt;fantasai> SebastianZ: you want feature detection for author so that they can migrate to nesting, so they're both entangled<br>
&lt;fantasai> ACTION: astearns to find path forward for this author-experience issue, whether to continue with this issue or make a new one<br>
