It seems to me Geometry is about shapes and shape operations and iteration.
QVM has nothing to do with shapes or iteration, but it defines a complete
set of generic namespace-scope quaternion/matrix/vector operations, which
Geometry doesn't. I also think that it shouldn't: if you want to use such
operations with Geometry types just use the QVM adaptation machinery
