Package a Python wrapper and see how popular it becomes. Some reasons
against trying to standardize on fdlibm were explained here:
Bottom line is I suspect that when it comes to bit-for-bit
reproducibility, fewer people care about that x-platform than care
about it x-language on the box they use. Nothing wrong with different
modules for people with different desires.
