[Twisted-Python] Moving iocpsupport to an external package? Implications on Windows?

Looking at this PR: https://github.com/twisted/twisted/pull/1446 I see that iocpsupport was moved to a separate package, in order to make building wheels on Windows easier. Before this patch, I was prototyping building binary wheels on Windows of Twisted core, and I had it working. It looks like this code has now moved to: https://github.com/twisted/twisted-iocpsupport How will this patch change for people installing Twisted on Windows? Twisted is still used by a lot of users on Windows, and the IOCP Reactor is still used on this platform. -- Craig
