 It would be nice to have `wp_add_preload_resources()` but I'm not a fan of
 globals. It is the (very) old way of doing things and has many drawbacks.
 For example some plugin may start manipulating the global directly. Then
 if core decided to fix or change something, it will fail.

 Also this will fail if `wp_add_preload_resources()` is used after
 `wp_preload_resources()`, and the plugin using it will not even know.
 Worth mentioning in the docblock at least.
