UNS: [Moderator Action] Re: [css-device-adaptation] Progress?

I am currently "fighting" to find a simple way to make Google Mobile like  
my sites pages. I strive to have all HTML 5 pages have no errors and just  
one CSS file to control all. 
 
It seems like the CSS verifier currently doesn't support @viewport although 
 some of my test pages seem to actually function on the web as intended. 
 
I would like @viewport usage within an @media usage near the top of a CSS  
file. This seems natural to me to control mobile device  viewport, perhaps 
even multiple ones, at the highest level and in one place  vs within multiple 
HTML files. 
 
One of the recent comments, 26 Feb 2015, says:
 
" All in all, I see that there's a valid use case for permitting  @viewport
rules in external styles other than mere convenience.
So,  perhaps limiting @viewport rules to be one of the first rules in an
external  style (along with @charset and @import) would be enough, if
coupled with user  agent scanning those files to extract these rules, along
with console  warnings of possible performance issues.

Rune, Florian - WDYT?"
