While I would love less duplication in the numpy namespace, I don't think the
small gain here is worth the pain of deprecation.

I think it would be better to fix this issue. np.min(3,2) should also give
"ValueError: axis(=2) out of bounds". Fixing this also removes any possibility
of generating hard-to-find errors by overwriting the builtin min/max. (Unless
there's some corner case I'm missing).
