I would like to support both scenarios. Sometimes the games provide it's own version of quartz.dll with DirectX, and it will be great if Wine will support native quartz.dll (especially that we have workaround patch and it seems that the issue is solvable).
We can't really support using Microsoft DLLs in general; they're only available as workarounds in case builtin is broken. It's not really possible to debug Microsoft DLLs while still adhering to the clean room guidelines. If builtin quartz is broken, please file bugs for builtin quartz, so that it can be fixed.
