In fact Cython used to advertise a CythonBuildExt command (i forget of that's exactly the name) that overrides the default build_ext command to also compile Cython modules as needed.
This still exists in the Cython package, but they no longer document it. It doesn't do dependency checking, so it doesn't work as well as cythonize(). For example, packages using cysignals cannot be compiled using this custom build_ext class, only with cythonize().
That said, you still need to have a fallback for when Cython is missing.
I don't mind assuming that Cython is installed. It makes things a lot simpler.
