Comment (by neoxx):

 Sure thing, here you go:

 {{{#!php
 function wp_resource_hints($hints, $relation_type) {
         if ($relation_type=='preconnect') {
                 $hints[]='//example.org';
         }

         return $hints;
 }
 }}}

 Though, I currently use the following work-around:

 {{{#!php
 $protocol=(is_ssl()) ? 'https' : 'http';

 $hints[]=$protocol.'://example.org';
 }}}
