At this point, I'm not sure I ever will. I encoded the "enabled" part into the value with a high bit (1<<24) -- not sure that was such a great idea. All NVIDIA hardware supports colorkey (and not actual alpha, until the very latest GPUs - Volta/Turing families), although my implementation only covers the pre-G80 series (i.e. DX9 and earlier GPUs - pre-2008). Should a determination of usefulness be reached, it would be easy to implement on the remainder though.
