By the way we started to move these network hints code outside chrome into
content + mojo (See crbug.com/610750).  In our case I feel it's even less clear
why we need to go through chrome... we probably don't need to?

I just wanted to align with DnsPrefetch and Preconnect.
But this completely conflicts with crbug.com/610750.

Do you have any idea about when crbug.com/610750 will be fixed?
