// First, we remove all the RSS feed links from wp_head using remove_action

// Resource Hints is a rather new W3C specification that “defines the dns-prefetch,
// preconnect, prefetch, and prerender relationships of the HTML Link Element (<link>)”.
// These can be used to assist the browser in the decision process of which origins it
// should connect to, and which resources it should fetch and preprocess to improve page performance.

// Sends a Link header for the REST API.

// Outputs the REST API link tag into page header.

// WordPress Page/Post Shortlinks
// URL shortening is sometimes useful, but this automatic ugly url
// in your header is useless. There is no reason to keep this. None.
remove_action( 'wp_head', 'wp_shortlink_wp_head');

// Weblog Client Link
// Are you editing your WordPress blog using your browser?
// Then you are not using a blog client and this link can probably be removed.
// This link is also used by a few 3rd party sites/programs that use the XML-RPC request formats.
// One example is the Flickr API. So if you start having trouble with a 3rd party service that
// updates your blog, add this back in. Otherwise, remove it.
remove_action ('wp_head', 'rsd_link');

// Windows Live Writer Manifest Link
// If you don’t know what Windows Live Writer is (it’s another blog editing client), then remove this link.
remove_action( 'wp_head', 'wlwmanifest_link');

// WordPress Generator (with version information)
// This announces that you are running WordPress and what version you are using. It serves no purpose.
remove_action('wp_head', 'wp_generator');
