Equipping it and using an icarus wing to regain mp in an oshit situation is an option, I'll give you that. It's not one I'd use myself (never been necessary), nor would I recommend making the staff for that reason alone. But if you already have the staff or want to make one anyway, sure, nothing wrong with keeping a wing in your inventory if you have room for it.
