@AlexHofbeck i’ve missed your reply while writing mine due to crappy internet 
I’ll reformulate the question: do you expect comments made in a federated view to belong to only one of the models in that view?
This will be rather difficult for us to enable, as we assumed a comment in an federated view will be relevant in that specific context, e.g. structure misaligns with architecture > to understand that misalignment you need both models.
