Re: [webcomponents] [Shadow]: Add "closed" flag to createShadowRoot (bugzilla: 20144) (#100)

@dylanb I have a bunch of use cases for which iframes are terribly cumbersome due to lack of a formal API and styling issues: ads, single authentication, embedded content (youtube, twitter-streams, Discourse) and payment windows.
Have a look at the trouble this guy went through to support something that should be first-citizen on the web: http://benvinegar.github.io/seamless-talk/#/

I don't now the implementation details of this, but what makes you think you won't be able to detect a shadow DOM? I can imagine a simple test would do.
Again, I don't know the details, but I don't see a conflict. As I understand it, this simply opens up more browser internals to web developers. I would guess that the underlying sandboxing is the same as used by iframes.
