That's correct. You may be able to use one of the existing tables or make a new one, but either way if the table doesn't exist, if the configuration storage database doesn't, or if they aren't configured you'll need to just disable the feature.
A good example of how that is handled already is with the internal relations feature that works similar to InnoDB relations.
You've got the right idea, though. If the user doesn't have the proper table structure or has disabled the feature in config.inc.php then we should just disable the enhancement entirely.
Does that help?
