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).
