"""When serializing many annotations pointing to the same entity, it is expensive to
repeatedly look up and serialize the same entity.
TODO: if Entity were a (nullable) foreign key of Annotation, we could just:
prefetch_related('entity', 'entity__user', 'entity__documents')
before serializing the annotations, which would make self.entity.json(user=user) cheap and
all this unnecessary.
