Wrong way to overwrite a menu declared by another module

In Drupal 6, the correct way to overwrite a menu defined by another module is to implement hook_alter_menu().
This is not what the module does, when it define its own menu callbacks.

  $items['blog'] = array('title' => t(''),
  'page callback' => 'blog_addons_bloggers',
  'access arguments' => array('access content'),
  'type' => MENU_CALLBACK,
);
