The situation betwen druntime and Phobos with regards to Windows-specific
stuff definitely needs to be ironed out. The two conflict and at least some of
the Phobos stuff for Windows isn't even under Boost. So, there's work to be
done there. However, I don't believe that any Phobos developers are focusing
on Windows-specific stuff like this at this point. So, if the situation is
going to improve, someone is likely going to have to step up and do the work
and then submit it for review. Otherwise, it's not likely to improve much
anytime soon. Various pull requests from folks outside of the Phobos dev team
have certainly helped, so progress is better than it was, but someone is
probably going to have to take it upon themselves to sort it all out and
propose and implement an appropriate solution for it to get fully fixed.
