To be slightly fair, it's only two point in the Smithing tree to be able to improve magical stuff. It's still shit, though. I need all the points I can get.
Presumably at some point someone will come up with a mod that gives the NPCs the ability to do it.
They should never be able to fly with wings that small, though. And surely, if I'm pinging arrows into them, there's a fairly good chance I'd hit the flammable stuff they breath and they'd explode.
On the plus side, they really don't like mudcrabs.
