It's not clear how to embed such information deterministically into
the so/dll file (which are produced by the C compilers), but if you
had/could create the generated C files we do put some metadata at the
top of those when compiled with cythonize, e.g.
/* BEGIN: Cython Metadata
[JSON data about cimports, distutils options, etc]
END: Cython Metadata */
We could consider putting imports there as well.
