WordPress settings I use

I don’t like the “garbage” code in the project (lol, so why you using WordPress :)) and that’s why I add in functions.php file of my theme the following code:

# Disable XML-RPC RSD link
remove_action('wp_head', 'rsd_link');
# /Disable XML-RPC RSD link

# Remove api.w.org relation link
remove_action('wp_head', 'rest_output_link_wp_head', 10);
remove_action('wp_head', 'wp_oembed_add_discovery_links', 10);
remove_action('template_redirect', 'rest_output_link_header', 11, 0);
# /Remove api.w.org relation link

# Disabling emoji library from WordPress
function disable_emojis()
{
remove_action('wp_head', 'print_emoji_detection_script', 7);
remove_action('admin_print_scripts', 'print_emoji_detection_script');
remove_action('wp_print_styles', 'print_emoji_styles');
remove_action('admin_print_styles', 'print_emoji_styles');
remove_filter('the_content_feed', 'wp_staticize_emoji');
remove_filter('comment_text_rss', 'wp_staticize_emoji');
remove_filter('wp_mail', 'wp_staticize_emoji_for_email');
add_filter('tiny_mce_plugins', 'disable_emojis_tinymce');
add_filter('wp_resource_hints', 'disable_emojis_remove_dns_prefetch', 10, 2);
}
add_action('init', 'disable_emojis');
# /Disabling emoji library from WordPress

# Filter funcion to remove the emoji plugin from TinyMCE
function disable_emojis_tinymce($plugins)
{
if (is_array($plugins)) {
return array_diff($plugins, array('wpemoji'));
} else return array();
}
# /Filter funcion to remove the emoji plugin from TinyMCE

# Removing emoji CDN hostname from DNS prefetching hints
function disable_emojis_remove_dns_prefetch($urls, $relation_type)
{
if ('dns-prefetch' == $relation_type) {
/** This filter is documented in wp-includes/formatting.php */
$emoji_svg_url = apply_filters('emoji_svg_url', 'https://s.w.org/images/core/emoji/2/svg/');
$urls = array_diff($urls, array($emoji_svg_url));
}
return $urls;
}
# /Removing emoji CDN hostname from DNS prefetching hints

# Disable RSS Feeds
function wpb_disable_feed()
{
wp_die(__('No feed available,please visit our homepage!'));
}
add_action('do_feed', 'wpb_disable_feed', 1);
add_action('do_feed_rdf', 'wpb_disable_feed', 1);
add_action('do_feed_rss', 'wpb_disable_feed', 1);
add_action('do_feed_rss2', 'wpb_disable_feed', 1);
add_action('do_feed_atom', 'wpb_disable_feed', 1);
add_action('do_feed_rss2_comments', 'wpb_disable_feed', 1);
add_action('do_feed_atom_comments', 'wpb_disable_feed', 1);
# /Disable RSS Feeds

# Disable author page
function disable_author_page()
{
global $wp_query;
if (is_author()) {
# Redirect to homepage, set status to 301 permenant redirect
# Function defaults to 302 temporary redirect
wp_redirect(get_option('home'), 301);
exit;
}
}
add_action('template_redirect', 'disable_author_page');
# /Disable author page
