My point is that your "Windows build" would not have the same behaviour
as a MSVC-produced Windows build, and so testing it with it would not
certify that your code would actually be compatible with genuine
MSVC builds of CPython, which we will not stop supporting.
Therefore, what you and the OP are proposing would not make it
*easier* to ensure cross-platform compatibility but rather *harder*, by
adding another incompatible build configuration to the mix of supported
The only remaining question is whether it is worthwhile adding support
for such an additional platform, and given that MinGW is extremely
marginal amongst Windows developers, the answer is IMHO no.
