Doesn't the documentation ever mention Cython? It probably should (no idea about pybind11, which I've never played with). Perhaps you can open an issue about that? As a sidenote, you can certainly use Cython without learning the C API, but to extract maximum performance it's better to know the C API anyway, to be aware of what kind of optimizations are available in which situations.
