Yes, we would need to continue providing a version for Windows. It would be a relatively small change to move it to the externals repository. I would be fine with switching to `--with-system-expat=yes` by default and building from externals on Windows in 3.7, and removing the bundled expat in 3.8. >> By the way, Zachary Ware is working on converting this repository to >> Git.
