Re: [csswg-drafts] [css-shadow-parts-1] Can class name selectors apply to a part? (#3431)

Understood. But _updating_ that DOM state from JavaScript would slow things down for interactive pseudoclasses that change a lot. (Like the example in the webcomponents issue for re-implementing `:hover` with mouse event handlers.)
