Comment (by nico23):

 I am confused about this. I have not digged though the source but looking
 at the patch it seems the URL is hard-coded in. However, if I got this
 right, people say we can set the referer with in the $args['headers'] the
 screenshot above shows code like this and the codex says the arrays should
 contains a array with header lines. However I have seen a lot of code that
 uses key-value pairs in the array so my questions are.

 1. Can I set the referer with the $args on wp_remote_get/post.
 2. If yes, do both of this ways work?
 3. Any easy way to test this?

 {{{#!php
 <?php
         $referer = site_url();

         $wp_remote_get_args = array(
                 'headers' => array( "Referer: $referer\r\n" );
         );
 }}}


 {{{#!php
 <?php
         $wp_remote_get_args = array(
                 'headers' => array( 'Referer' => site_url() )
         );

         $response = wp_remote_get( $api_url, $wp_remote_get_args );
 }}}

 And yeah seems @rmccue does not really care to fix this upstream and seems
 people not really need this, that Github issue is not really getting much
 attention.
