Define gone, because half the community would disagree with you there. If you're having to disable it for rudimentary purposes then there is still problems with it. Ones that are easily avoided, but that doesn't make it somehow a non issue. Clock jumping is still very much an annoyance without user intervention. Simple things like this may benefit from such technologies was my initial point
The performance gain from disabling it is negligible these days. The only benefit is to gain monitoring of gpu metrics and allowing you to alter voltage control for the second (ULPS enabled) gpu.
What clock jumping are you referring to?
