Binary wheels which bundle compiled non-Python dependencies using tools such as auditwheel are extremely fragile, as there is nothing preventing the user from installing a package which might bundle a different version of the same library, resulting in hard-to-debug erratic runtime errors due to ABI inconsistencies, symbol collisions, etc. The scipy situation is not the same, as, to my knowledge, scipy's depends only on widely available libraries with simple and stable ABIs (e.g., BLAS, lapack). I do not think it's realistic to expect to be able to sanely manage a multi-language software distribution with language-specific package managers.
