Upscaling is more useful if you need some crazy framerates (like 240 fps) with high graphics settings for some reason. Even most high end GPUs can't handle that for demanding games on common resolutions. Or more reasonably for mid range and lower end GPUs which are just weaker and can't handle even 144 fps for the above without upscaling. But low end GPUs use case isn't relevant for streaming since they can have highest end ones. So we are talking about those who want to push those crazy framerates, and I don't think networks allow that even if GPUs can sustain them. Some middle case can happen I suppose if you get an outlier super demanding game, but I always saw it as questionable to push max settings if you are ready to trade image quality for more framerate with upscaling anyway. I'd rather stick to lower framerate and keep image quality of max settings intact by avoiding upscaling. So I just don't see a value in having it, let alone in dedicated hardware vs something like FSR which can work on regular compute units.
