Comment (by furi3r):

 Thanks for your feedback @swissspidy.

 Regarding filter vs imperative way, I agree with you that filter may not
 be the most intuitive way, but at this stage, and following the current
 ''wp_resource_hints'', I would go down this path for now, and maybe in a
 separate ticket, create imperative functionality, I wouldn't like to see
 this ticket stale for another 5 years.

 Regarding core functionality using this preload feature, I'm not sure
 about that, but I'm sure this will be helpful for
 theme/plugins/performance developers, IMHO I don't see why offering this
 extra possibility could hurt core, it's a nice benefit to have for whoever
 wants to use it.
