I think you didn't get the point. The """""""current""""""" taxonomic opinion (or most of the current ones) is (are) ALWAYS a personal opinion.
I considere the Struthioniformes including all ratites except Tinamidae as the current taxonomic opinion (formerly each family had their own order (except Casuariidae and Dromaiidae in the same order), but the global consensus appreciation changed after to unite all them in a single order). I considere Casuariidae and Dromaiidae as separated (but very closely related) families as the current taxonomic opinion, it's the most universally accepted like in the previous case. And, I also consider that Struthio is a monotypic genus with a single extant species (plus some more fossil species), being Struthio camelus molybdophanes a subspecies of Struthio camelus, and of the current taxonomic opinions this is the most widely accepted by far.
