As an outsider, I have to say that this sounds perfectly fine - even desired. Not following the QAIM protocols pedantically will have all sorts of unintended issues otherwise, some of which are hard to spot and test for. I can only recommend to test every model with the QAbstractItemModelTester, which will probably also complain about the above situation from what I understand.
