I like the idea, but I don't really see why this would change the 'Builder' population. Gamers would love it (I have a Windows 10 install around for gaming, I'd take this in a flash, I'd probably not even complain too much about the money), but that isn't the same. To make it work for builders it needs to be an attractive place to do development and I don't see how this really helps with that (other than maybe improving the audience for their products). Although I am speculating there - I haven't written any code on Windows for maybe 15 years now and I don't expect ever to do so again.
