AFAIK it's a huge pain to keep the win32.mak up-to-date and requires a lot of work & resources that would be spent more wisely on important matters.
Ideas
1) use reggae (or another cross-platform buildtool) for dlang.org
2) just drop win32.mak (windows 10 includes a full ubuntu bash anyways)

I don't think this is really an option. Windows 10 bash produces posix executables, not windows ones. So it is only ok if posix.mak can be used to cross-compile for windows. Even if that is the case, the Windows 10 bash currently has some limitations that make it not production-ready.
