You can go a surprisingly long way with Python's built-in and stdlib
containers, so I'm not surprised it's not very widely used.

I don't know what wheels are supposed to change here.  You could already
build binary packages for Windows before wheels existed.  The problem as
I understand it is that you need a Windows machine (or VM) together with
the required set of compilers, and have to take the time to run the

With conda-forge though, one could simply submit a recipe and have all
builds done automatically in the cloud.  Your users then have to use
conda (rather than pip and virtualenv).
