To put it in perspective: an average eye blink is 100-150 ms. The worst outcome in this test was with XWayland adding 3ms of latency. Maybe this is truly important for some exceptional pro gamers but for the majority of the world it is as you say, stupid and pointless.

This was with a nvidia 4070 attached to a 500 hz monitor. Even so P95 difference between worst and best was closes to 5ms. Meanwhile 60 hz monitors are incredibly common and every time a 16.7 ms frame deadline it causes an additional 16 ms of latency worse this is inconsistent and spiky and will be noticeable.

The length of a blink is irrelevant. People notice latency especially inconsistent latency. The perception of xwayland being laggy in latency sensitive context like gaming is accurate.
