Poor D3D support currently, will it be improved?

I found the D3D wrapper missing lot of gl???? functions, will it be completed in near furture?

Especially, the stencil support is completly missed, although I have put by my own. I found glTexEnvf with GL_COMBINE_RGB_EXT also not supported and making some multi-texture effect look missing.

Will it be completed?

I found there are lot of people using quite old display, which doesn't support OpenGL. It is necessary to support D3D as it is almost 100% supported.
