Yes, it could be a part of my GSoC project to add missing support for
DDS file format in D3DX9. Anyway, I will know what's missing after
seeing Christian's patches.

That's right. WIC decoder for DDS is not the best idea. In case of,
D3DXGetImageInfoFromFile you need potentially to get the following
info from a file:
* type of texture: plain texture, cube texture or volume texture
* number of mipmaps
* depth of volume texture
* texture compression format.
You're unable to get this information through a WIC decoder interface.
