Both work very similarly. Management just means extra options under the Manage button for the client. For shared hosting panels, users can just login to the panel to perform actions so it's usually not an issue. For Config Options, it just means that the module is not expecting any configurable options that would change the way it provisions the account through the DA API.. for example, extra disk quota, mailboxes, etc. That's not supported, so the accounts will be provisioned based on your Package settings.
