Re: [csswg-drafts] [css-nesting-1] Relaxed nesting and var() (#9317) from Matthew Dean via GitHub on 2023-10-07 (public-css-archive@w3.org from October 2023)

Also... I thought the CSS Nesting spec specifically omitted as ident start for very good reasons of avoiding infinite ambiguity. Is there really a big problem just requiring this?
```css
.foo {
  :is(div) {}
}
```
or:
```css
.foo {
  & div {}
}
```
I don't understand the drive to create a new parsing / backtracking strategy and potentially break tooling to avoid typing `:is()` or `&`. What's driving this?
