My Portion...

you should probably go through another editing pass.
Well, that is not entirely true.  We also have a first-class C++ API that more and more folks are using that doesn't require Python to be installed on the system at all. We are thinking about adding portions in a Fortran API, too.  At some point we become not a Python project, but a Python/C++/Julia/etc project.  This is different than projects like numpy where the C-layer is could be described with words like 'disaster' and 'mad genius' :).
