Comment (by jonoaldersonwp):

 Browsers which don't support `preconnect` will fall back to `dns-prefetch`
 gracefully when both are included, and `preconnect` 'includes' `dns-
 prefetch`. So having both is good practices.

 I'd be nervous about doing this globally, as there's a cost to (either)
 hint if/when it's not used.

 We should do this regardless of caching, as the browser still needs to do
 the HTTPS handshake, etc, and getting that started sooner saves a bunch of
 time.
