Why did you remove this opening sentence? I think the caveat about new policies
should come after this, instead of being the first thing in the page. WDYT?

I felt it was redundant since the title of the wiki page already says "Policy
List" and the page starts with the sentence "Last updated for Chrome 34."  It's
only after this, that the sentence in braces starts.  Please have a look:

Makes sense, thanks for explaining.
