And, crucially, the character of Osgood still debuted in The Day of the Doctor. Further "incarnations" may have come afterwards, the idea of multiple Osgoods all being (authentically) Osgood may have come from a later story, but Osgood still debuted in Day. I agree that there should be no issue with this choice of disambiguation.
