that's true, but the delay there is significantly higher usually. The time to encode a frame usually guarantees at the very least 15ms, even with hardware encoding at low quality, but previously there was like 9ms of latency to steamVR. This is significant because it might mean some kind of async render. 
Also wifi6e has a potential of 1ms if the quest 2 is the only thing on your AX router's 5g (it'll go up if other devices use it)
That in itself is really exciting.
