That’s only on a cold start.
Comment on Kia drops the ball again on their vehicles

Basically the engine experiences the most wear when starting, because it doesn’t yet have oil pressure. That takes around 7 seconds with the engine featured in the video.

Typically it experiences most wear at start because the oil isn’t up to temperature. When stopped at a red light, oil is still coating all the components, so while the pressure may be low, it will only be a momentary increase in wear. 7 seconds is very little compared to the time it takes the engine to get up to temperature on a cold morning, which is wear the majority of wear will still come from.
These systems have been in common use for like 15 years or something, and first became commercially available over 25 years ago. We’d have actual hard evidence if it were causing excess wear.
