domenic has just created a new issue for https://github.com/w3c/csswg-drafts:
== [css-nesting-1] Consider using ObservableArray<CSSRule> instead of CSSRuleList ==
https://w3c.github.io/csswg-drafts/css-nesting/#cssom-style
I think this would be nicer as
```webidl
partial interface CSSStyleRule {
attribute ObservableArray<CSSRule> cssRules;
};
```
This:
* Ensures that `cssRules` has all the nice `Array` methods, e.g. `map()`, `filter()`, etc.
* Removes the confusing `item()` method.
* Allows manipulating the CSS rules using normal array methods, e.g. `rule.cssRules.pop()`, `rule.cssRules.splice(4, 1)`, etc.
* Allows completing replacing the rules list, e.g. `rule.cssRules = [newRule1, newRule2]`.
You could optionally keep `insertRule()` and `deleteRule()`, but they would probably be less necessary. (Although I guess there's no other way to go from string -> `CSSRule`?)
/cc @tabatkins as someone interested in array-like design on the web platform.
