That seems fine, but it does mean that builtin elements have "magic" place for storing such data. Basically for builtin elements for which you can call `attachShadow()` there's four places: magic internal slot -> shadow tree slot -> element AOM slot -> element ARIA slot. For custom elements there's three places: shadow tree slot -> element AOM slot -> element ARIA slot.
