If we really can't get the windows support working before the next release then making it disabled by default on that platform makes sense and in that case it is probably simpler to make the default the same across all platforms. It would be nice to get the windows side working, I had assumed that would be fairly easy because the patches exist in Ezekiel's series but maybe I'm missing something. I'm also hopeless at keeping track of when the next release is so maybe there isn't much time.
