[w3c/webcomponents] Why allow shadow root style to access :host? (#490)

Why is this allowed? It seems like if I place DOM from an unknown source in my shadow root that one of the main advantages would be encapsulating that unknown DOM so it can not escape the encapsulation. I wouldn't want it to apply arbitrary style to my shadow host.

What's the advantage of allowing `:host` access via CSS?
