Well, it isn't even a standard yet. Google wants to push it just to have it for Angular.
Maybe, but that doesn't mean Google cares about enpowering the web platform in general.
If they did they wouldn't have removed other standard code (css regions), and they wouldn't have pushed for their, non-standard, Shadow DOM implementation.
Anyways, I really think people are sort of attributing malice to Glazkov's remarks where none really ever existed, WRT shipping the shadow DOM in its current state.
