To be honest this is very much a bouldering/rock-climbing question but hardly a question about the outdoors. Let me know if there is a better home for it.
It seems like it should be very easy for indoor gyms to synthesize boulder problems that match or exceed the v17 grade. Although only a handful of people on the entire planet would be able to do them, certainly they could be "attempted".
I was surprised that I couldn't find a SINGLE example of this across google and youtube outside of 3D printing the holds of Burden of Dreams and mounting them on a correctly angled wall.
Why hasn't this been done yet?
