If all objects become top-level objects and if all objects are referenced (not embedded), then we cannot assume that all objects will be actually available or shared at the same time that their relationships are shared. It is quite possible that a relationship is shared but the STIX data object it refers to is not.
POTENTIAL ANSWER
This will be fixed if we allow STIX Request and Response packages #66. See the commentary discussed in the 'Difficult to ask a request and get a response to that question' section
