So, should we consider this a problem? The lib path looks like it will be
filled with a bit of junk... although it's probably benign.

Well, I have only argued for the DXSDK, because it's an official Microsoft
supplied lib with tight integration into their ecosystem, and it has since been
merged into the Windows SDK, which created the disparity between new and old
versions of Visual Studio.

Did you have one in mind? I haven't come in contact with any others that I feel
make such a strong case.
