Thats your risk that you are apparently willing to take, it should not be used for production purposes, you might get lucky you might not, if not the answer will be a shrug of the shoulders and a DUH
Why are you insisting that it's so bad to use? It is a DEVELOPER version, it's purpose is to allow developers early access to Windows 8 to develop apps, already. If that is not a production purpose in it's own, then what?
Besides what's the risk of it anyway. You won't hurt your system, it might not run some things or not at all or everything just fine. That's all.
