If you mean just moving the existing git repo under the numpy
organization, like github.com/numpy/numpy-vbench, then I'm not sure
how much difference it would make really. What seems like it'd be
really useful though would be if the code could move into the main
numpy tree, so that people could submit both benchmarks and
optimizations within a single PR.

Cool!
