Re: [w3c/webcomponents] Need a callback for when children changed or parser finished parsing children (#809)

As with #550, I do not support this if it is parser-specific. If it is just a CEReactions-time MutationObserver that only custom elements can install, then I'm open to investigating. In that case I think we should also seriously consider un-deprecating `DOMNodeRemoved`/`DOMNodeInserted` as an API shape, since that already exists in some browsers and we've needed to spec it properly for some time.
