Nested ZClasses are automatically addable to the ZClass ObjectManager
they were created in. Nesting a ZClass is an explicit operation with
that goal in mind, a nested ZClass cannot be added anywhere else. An
extra, explicit step to make them addable to the parent ZClass
ObjectManager is therefore unnecessary.
