Yes, for sure. The manual is bit lying. :-) The cost of grafting is typically very low, and order of magnitudes lower than a full rebuild of the dependency chain. But if grafts is here, it is because of something. Therefore, I do not understand what it does mean “ungraft”. Avoid the grafting mechanism when it is possible? All the best, simon
