[Openstack] Accessing instance.flavor.projects fails due to orphaned Flavor

The flavor field of the Instance object is a lazy-loaded field and the 
projects field of the Flavor object is also lazy-loaded. Now it seems 
to me that when the Instance object lazy loads instance.flavor then the 
created Flavor object is orphaned [1] therefore 
instance.flavor.projects will never work and result in an exceptuion: 
OrphanedObjectError: Cannot call _load_projects on orphaned Flavor 

Is the Flavor left orphaned by intention or it is a bug?

The payload of instance.<action> notifications contains the flavor 
related data of the instance in question and to have the 
flavor.projects in the payload as well the code would need to access 
the projects field via instance.flavor.projects.
