[webkit-dev] HTML5 & Web Links (RFC 5988)

[Antti Koivisto]

Even for prefetching this seem rather worthless as it won't allow
prefetching start significantly earlier over the resources specified
in the document source.

There is also (based on the experience in similar things) a high
chance that whatever is listed in the Link header won't match what the
document actually uses and so will end up slowing down the page load.
