The windows driver does advertise this extension. As the attached patch shows, the comment in the code already says it should be supported, but the chip revision check is incomplete.
I couldn't test the patch, as the only program actually using this extension that I know of is unigine, but it also needs GL_EXT_texture_swizzle (which is supported by the windows driver).
