Whoa, I thought you were asking for clarification here, not actually arguing about validity of current design.

Shadow DOM is just DOM, period. There's nothing to argue here. The way it is implemented currently is backwards.

The absence of JS wrappers has little to do with the matter, since shadow DOM elements still participate in the rest of lifecycle, including events, attachment, detachment, tree and document insertion/removal. Getting it right in the current design is extremely difficult, tricky, and brittle. Arguing for this being hand-coded instead of using standard DOM machinery seems... Halloweeney? :)
