You can define almost anything as a security risk. But we aren't children to play such stupid games.
We are talking about someone gaining that information and the probability of that happening without even knowing what security mesaures will be in place. I think the risk is negligible even today with the limited information about it that we have now. Other People here, presumably you as well are hysterical about it.
Thats what the discussion is. You actually believe Microsoft will launch this and then everybody will be hacked or something. I think that is... not smart.
