Do we need another catogary of fly?

[AlanB]

Generally flies are as nymphs, streamers, wet flies, emergers, and dry flies. Originally flies were fished dry until they became waterlogged, then fished wet. Then came flies intended to be fished as dry flies. Almost without exception these flies didn't float (displace a greater weight of water than their own weight), but stood on the meniscus. (I do not want to reopen the debate about how flies stand on the water, but I think we can agree that they do).

Now we have modern materials that are both buoyant and flexible enough to be to be incorporated into a fly. It could be argued that these are not the same as the traditional dry fly. Should we catagorise these flies seperatly, perhaps as "Buoyant Flies"?
