Thanks Auke! One of the best lists I've seen.

We were inspired to make a free plugin recently, would appreciate any feedback:

It appears that you're adding a filter here, but there is no matching function named "disable_embeds_rewrites" being declared.

A quick Google search returns a Kinsta article that uses this same filter and has some more complete code.

function disable_embeds_rewrites($rules) {
    foreach($rules as $rule => $rewrite) {
        if(false !== strpos($rewrite, 'embed=true')) {
            unset($rules[$rule]);
        }
    }
    return $rules;
}

Some parameters can be redundant like in remove_action( 'wp_head', 'rest_output_link_wp_head', 10 ); third param "priority" has 10 as default value, so you don't have to write it again.

wlwmanifest_link is deprecated in 6.3.0 and no longer included in core so it might be redundant to add.
