I wonder about this too. I can imagine there are a reasonable number
of people using older Linux distributions on which they cannot upgrade
to a recent Python 3, but is that likely to be true for Windows?
We'd have to make sure we could persuade pypi to give the older
version for Windows, by default - I don't know if that is possible.
