I think they could be useful.
My vote is for a 3d print. 
These would be brilliant for many small companies stuggeling to get a working shoulder deformation rig. Having reference scans like this could really help in setting up morph targets/blend shapes - or even just as reference. I know that when I faced the problem of setting up a working shoulder system these would have been invaluable.
edit: for some reason the shoulder image appeared in the zbrush feed so this reply is in regard to those, I didn’t notice the thread had advanced so far since then. 
Hey guys.
