I think it would kill the scene, Stadia is anti-performance, it's a video feed streamed over the internet, with all the problems associated with processing on a remote computer, the primary motivator for high refresh rate monitors and low latency input is FPS games I would assume, so going from sub 10ms end to end latency to a 40ms latency on a perfect connection, I just don't see it being accepted.

As an aside it's recommended to keep latency under 20ms to stop motion sickness in VR.
