Add ability to developers to add their own plugin statuses via a filter #1

[pexlechris]

My suggestion is to add ability to developers to alter/filter the allowed plugin statuses .

So If you add a WP filter, this could be done more efficient and natively.

My code suggestion is this:
in file:
wp-admin/includes/class-wp-plugins-list-table.php
in construct method to add a filter after defining the $allowed_statuses variable like this:

/**
 * Filters the plugin allowed statuses.
 *
 * @param array $allowed_statuses The array of plugin allowed statuses.
 */
$allowed_statuses = apply_filters('plugin_allowed_statuses', $allowed_statuses);

For example, my case was to add plugin status fav_plugins, and I have written this work around to init the plugin_status as I need:

<?php
// Workaround
add_filter('plugins_auto_update_enabled', function($enabled){
        if( !is_admin() ) return $enabled;

        global $pagenow;
        if( $pagenow != 'plugins.php' ) return $enabled;

        $plugin_status = $_GET['plugin_status'] ?? '';
        if( $plugin_status != 'fav_plugins' ) return $enabled;

        $GLOBALS['status'] = 'fav_plugins';

        return $enabled;
});

My purpose was to create a functionality to save all the active plugins to a newplugin status called fav_plugins. You can view the plugin I created here:
