Disable D7-toolbar for AM users

I wanted AM for myself, but toolbar.module for other admins. Used this:

function MY_MODULE_menu_page_alter (&$page) {
  global $user;
  if ($user->uid == 1) {
  $page['page_top']['toolbar'] = array(
    '#access' => FALSE,
  );
  }
}

And enabled both AM and toolbar but no AM permissions for other roles. Works perfectly.
Is this a good approach?
Personally I think since toolbar comes default in D7, giving AM permissions should automatically disable toolbar for that role, since its obvious the two cannot coexist, and an admin wouldnt be enabling AM if he didnt want to use it. Makes sense?
