Sometimes during entity creation there are cases where you still want to create the entity, but don't want to create a missing related entity. Having this flag would allow for this use case. The entity would be created with the relation identifier included. This would put the entity in a state that is no different than when you delete an entity that is related to another entity and don't delete dependents. The identifier is still in the relation. If the related entity is recreated at some point, the two entities will now have that relationship.
