Multi-version wheels are a possible future extension, but I don't know if
anyone has thought about fine-grained tags.

I'm reasonably confident the wheel format *doesn't* meet the scientific
community's needs in the general case, and can't be made to do so without a
lot of additional complexity. That's why I explicitly support the
hashdist/conda approach which abandons some of the goals of pip and wheel
(notably, easier handling of security updates and easier conversion to
Linux distro packages) in order to better handle complex binary

another downstream "system" package manager to interoperate with.
