I could argue that it does have something to do with it, at least for 
ZODB.  ZODB considers objects not reachable from the storage root to be 
garbage, so at least that aspect of containment is relevant.  And from a GC 
point of view, if the persistence system treats parent references as not 
increasing refcount, then storages can efficiently release non-cyclical 
garbage.
