 In #34292 @superpoincare raised some concerns about hinting items in the
 HTML header, arguing it was of use to hint items in the footer only as the
 browser will connect to resources enqueued in the HTML header quickly
 regardless.

 @swissspidy pointed out "Even when enqueued in the head of the document,
 the resource hints will be delivered to the browser much earlier because
 their higher up in the source and therefore likely in another HTTP packet.
 Already being able to perform all necessary handshakes only benefits the
 actual retrieval of the assets later on."

 @peterwilsoncc thought there was some validitaty to skipping hinting on
 items in the HTML header but it's something that can be decided later. Oh,
 that's me.
