Re: [csswg-drafts] [css-scoping-1] should shadow-piercing descendant combinator (>>>) still be in specification

A page author can add an ID on an element to uniquely identify the element in a page, even with Shadow DOM. The problem @dylanb is raising is whether third-party tool (other than the page author itself) can address any element uniquely.

IMHO, the web platform is already providing a way to uniquely identifying an element, so this could be a hard ask for web platform to add solution for the requirement, unless the use case is also viable for web authors. (this question is also true for `>>>`, which this issue is about.)
