Comment (by voldemortensen):

 My initial thoughts are this is a great improvement. But then I thought
 some more. I don't know how browsers are implementing this. If I were
 implementing dns-prefetch, I'd ignore the scheme altogether because the
 scheme has no effect on DNS. However, I didn't do it, so I don't know.
 It's probably more safe to err on the side of caution here to avoid
 unnecessary CPU usage/bandwidth/etc. So +1 for dns-prefetching only.

 Theoretically:
 {{{#!php
 <link rel="prerender" href="http://site.com/post-name">
 <link rel="prerender" href="https://site.com/post-name">
 }}}

 can be different, so we should probably leave those alone unless we want
 to try and keep people from doing unintended things.
