I was reading the post by @zigpress about removing unnecessary emoji code and have implemented that procedure on all my sites. But in looking at my source code, I can see there are also calls to include remote-access and pingback functionality in these lines:
<link rel="EditURI" type="application/rsd+xml" title="RSD" href="https://digwp.com/xmlrpc.php?rsd" /> <link rel="wlwmanifest" type="application/wlwmanifest+xml" href="https://digwp.com/wp-includes/wlwmanifest.xml" />
Should these also be removed if they are never used? I have found it can be easily done with this code:
remove_action('wp_head', 'rsd_link'); remove_action('wp_head', 'wlwmanifest_link');
Is this worth doing?
