I don't entirely see the the point of this distro, but can see how it will be useful to some. Opensuse Tumbleweed is already pretty stable thanks to its testing.

I think corporations and individuals who need relatively new software but also want as stable a system as they can get may appreciate this.

My biggest concern is how are security fixes handled? Backporting patches will be difficult if the goal is to automate as of much of this as possible.
