Comment (by peterwilsoncc):

 I think using the existing code in `wp_resource_hints` would be better.

 The pros of using a separate function is that it is semantically correct.
 The cons are that it duplicates a near identical API; it's not possible to
 coordinate between preload and hinting to avoid double ups.

 If anyone feels strongly enough that there is a better name that can
 encompass both hinting and instructing the browser, the the existing name
 can be deprecated.
