 The `<head>` section contains a lot of `<link>` items that WordPress core
 generates.

 Why should themes be responsible for outputting the `pingback_url()`
 `<link>`?

 The core code should remove this burden from the theme and ensure that it
 is handled every time and correctly. Currently, the theme needs code like
 this:

 {{{
 function mytheme_pingback_header() {
         if ( is_singular() && pings_open() ) {
                 echo '<link rel="pingback" href="', esc_url( get_bloginfo(
 'pingback_url' ) ), '">';
         }
 }
 add_action( 'wp_head', 'mytheme_pingback_header' );
 }}}
 and a lot of themes don't even have it, so then there are core options
 that don't work correctly. This logic belongs in core.
