I think about the goal of "targeting Windows 7" as more about
revealing how Microsoft chose to implement these APIs on top of
MMDevAPI, than about replicating Windows 7's behavior exactly.
Targeting Windows 7 is the default choice when implementing these APIs
in Wine, and when we find applications that expect older behavior, we
can deviate from Windows 7's behavior to fix them specifically.
