@MorningStar1399 They could be in a guild -- merchants includes some, and I imagine healers might have the equivalent of flying ambulances. I did ask about a guild specifically for aeronauts, but I believe @ayzrules declined to make one. Furthermore, having the machine gift does not mean one must be an aeronaut, and being an aeronaut does not mean one must have the machine gift.
The issue of wings is an interesting one, and while this will need Ayz's confirmation, I suspect there are people who make or commission a pair just for the fun of it, if they have the gift of machine communication. Why not? For others, they may come in handy regardless of guild, and be worth the price of manufacture and maintenance. I mentioned that I'm pretty sure there's a portion in the military comprised exclusively of winged soldiers, who help maintain air superiority in a fight and are able to easily reach places otherwise accessed only with difficulty. *envisions a winged fellow fetching a cat down from a tree, instead of using a ladder* They'd be a boon to any police force or team of firefighters as well. However I also figure that there's any number of people with machine gifts that do not have mechanical wings, for one reason or another.
