Re: [resource-hints] Resource de-prioritization?

Blink also has a light tree pass that's part of the background parser
<https://code.google.com/p/chromium/codesearch#chromium/src/third_party/WebKit/Source/core/html/parser/BackgroundHTMLParser.cpp&sq=package:chromium&l=226>
that the preloader runs off of.  As long as the optional information was
tagged on the elements directly (not applied by styles) it shouldn't be too
hard to make blink skip preloading for the whole tree below it.
