Is Cython really necessary as a runtime dependency?

It has to do with compiling everything and packing the wheels for release. I don’t think there’s anything that I can do to change that.

Yes, it is required at build time. But I am 99% sure it is not required at runtime.

As fas as I can tell, cython is indeed not needed for the end users (who download the library as a wheel from PyPI).
So, I've removed the line install_requires=["cython"] from setup.py, see 7c1555f.

Anyone who wants to run python setup.py build_ext --inplace must have cython installed.
