Do not allow what?

Could we please avoid naming capabilities like ‘do_not_allow”?

$args = array(
			'labels' => $labels,
			'show_in_menu' => 'tools.php',
			'show_ui' => true,
			'public' => false,
			'capabilities' => array(
				'edit_post'          => 'activate_plugins',
				'edit_posts'         => 'activate_plugins',
				'edit_others_posts'  => 'activate_plugins',
				'publish_posts'      => 'do_not_allow',      <=WTH?
				'read_post'          => 'activate_plugins',
				'read_private_posts' => 'do_not_allow',       <=WTH?
				'delete_post'        => 'activate_plugins',
			),

it maps to nothing, has no meaning and causes lots of confusion when it shows up on the capabilities list. This is a very poor judgment IMHO.
