Overview
This is not true, the cython is needed also when there is incompatibility and you need to regenerate the content, ie like when we updated from cython 0.27 to 0.28 which broke quite few modules because they didn't have the dependency.
Cython generate the .c files, that are inside the tar. Why do you need to generate it inside the spec file? For example, this package will not generate any .c from .pyx for any cython version that you have installed, so in this case setting a random version of cython in the buildrequire or removing it will generate the same code.
I mean that you should pull in just cython, you don't need the version, that indeed is not required, in a case there is Cython 0.29 this package would suddenly break otherwise.
Uhm I really do not get why should require Cython (without version) when Cython is never called during the build process.
Upstream properly regenerates files if the Cython is present:
try: from Cython.Build import cythonize USE_CYTHON = True except ImportError: USE_CYTHON = False
And this avoids buildfails if the cython gets updated. Funny friendly issues like: https://build.opensuse.org/package/rdiff/devel:languages:python/python-http-parser?linkrev=base&rev=31
