That's a great narrative, except that in this case the "someone" in point 1 and the "browser developer" in point 2 are the same company, and the "competitors" from point 4 are not supporting the feature either.
Maybe let's wait for Apple to actually announce the details (which neither the cropped screenshot or the talk abstract have), and give the Chrome team some time to react and make a statement. Rather than have the 10th rehash of this on HN with an incendiary title.
