Generally, packages are compiled for the same processor generation as the corresponding Python. But not always -- e.g. NumPy opted for SSE2 even for Py2 to work around some compiler bug (https://github.com/numpy/numpy/issues/6428). I was bitten by that at an old machine once and found out that there is no way for `pip' to have checked for that. Besides, performance-oriented packages like the one mentioned could probably benefit from newer instructions.
You should probably resend this to distutils-sig instead of python-ideas -- that's where discussions about python packaging happen. (Python-ideas is more for discussions about the language itself.) -n -- Nathaniel J. Smith -- https://vorpus.org
