I saw that last hint today buveuse I misspelled a type name (dovecot-configurtation). I understand the hint is great when you forget to import a service module, but it's not so great when the error is misspelling. Maybe the solution would be: if the unbound variable is the name of a service, propose using that module, otherwise don't show any hint.
