This is a statement from the Chrome team; from Google. Since when does Google unilaterally decide on what it will or will not standardise in other browsers?
Standardisation is a multi-stakeholder collaborative process. This sounds very much like Google representatives don't view it as such. Given their dominant market position, that's a worrying sign.
These are not special-case subdomains, they are simply subdomains...
* The domain part of a URL is a critical security indicator.
* The shorter and simpler this indicator is, the more chance users will understand and trust it.
* Very few users trust www.yahoo.com while not trusting yahoo.com.
* If we assume that users who trust www.domain.com also trust domain.com and vice versa, we can remove the "www." from the UI, creating a shorter, simpler and more understandable security token.
Except when it's not.

Is there any record of this "consensus"? This shouldn't be happening, period. There is a difference between example.com and www.example.com: they can serve different content, and can have different DNS records. There is literally no sane reason to hide any subdomain, common or not -- it's there for a reason.
