Although I'm not very active around here much anymore, I was primarily
working on Windows things within the last few years.
While we have a lot of Windows users, we don't have a lot of Windows
contributors. The huge amount of churn necessary to make a change away
from VS, or the more likely move to make it possible to support both
VS and <insert other compiler>, seems like a large amount of work that
doesn't turn up much of a benefit. Especially for a platform with
constrained developer availability, working software trumps all, so I
don't expect that a project like this is going to see the regular
contributors shifting their focus away from improving Python as it is.
With that said, I do see the benefit of being able to build Python
with a free compiler. It would be great for us to be able to say it's
always built with free tools, but I'm not sure who's going to make
