That is correct - :root would be overloaded in this case (or simply called something else - like :scope). Isn't this how the combinator-leading selectors were proposed to work?

  // Finding all child, div, elements
  .querySelectorAll(":scope > div")

Looking through the archives it appears as if that's what Maciej proposed. If that's not the case - and the :root/:scope points back to the document root (?) then please disregard all of this, as it's no longer useful.
