I think it's fair to treat instancetype as an inherited requirement — that is, the rules of covariant override always apply, which essentially means that overriders of instance-returning methods must also return instancetype whether they say so explicitly or not.  But that's what I'd like Doug to weigh in about; it's possible there are exceptions to that that affect the analysis here.
