Wind is generally able to be forecast fairly well today. Applications sensitive to wind, especially to gusts, as light weight large side area vehicles will be, are going to be not usable when it's gusty. But that doesn't mean they're going to be not usable often enough to not be cost effective, and there may be options suitable to the specific mission to, for example, deliver a package simply nearby instead of at the destination.
There's also other design shapes, one of which I'm a little familiar with being Skylifter, that is saucer shaped. Their target audience is heavy lift, but they were very intent on minimizing wind effects and so chose that shape.
This specific shape though will be suitable a lot of the time for a lot of missions, and may even be more cost effective than a different shape - my non-CFD'd thought here is that the long skinny shape will likely get more lift from flow than a saucer. Maybe someone has done that research, as I'd love to read through it.
