Comment (by swissspidy):

 > Having the ability for developers to register and enqueue prefetch dns
 urls would be great.

 This could be achieved using a single filter, let's say `dns_prefetch`.
 I'm not sure it's worth to add this to core though, as it's not a big deal
 to manually print `<link rel="dns-prefetch" ...` on `wp_head`.
