Maybe hide discussion panel in block editor?

[joemaller]

Testing WP v6-RC1 and the discussion panel showed up even though post_type support had already been explicitly removed. Maybe their bug, maybe something we'll need to deal with.

If this sticks, we'll likely need to address this in JavaScript with this: (found here)

wp.data.dispatch('core/edit-post').removeEditorPanel('discussion-panel')

Added this to Extras\GlobalCommentsDisable based on some stuff in the Disable Comments plugin:

// in __construct
        /**
         * API, XMLRPC and REST comments
         */
        // add_filter('rest_endpoints', array($this, 'filter_rest_endpoints'));
        add_filter('rest_pre_insert_comment', '__return_false');
        add_filter('xmlrpc_methods', [$this, 'unset_xmlrpc_comments']);

// added this method:

    /**
     * @link https://developer.wordpress.org/reference/classes/wp_xmlrpc_server/__construct/
     */
    public function unset_xmlrpc_comments($methods)
    {
        unset($methods['wp.newComment']);
        return $methods;
    }
