I find it in keeping with the Stanford study people are mistakenly freaking out over.

1. It's probably a good thing, once you realize it means COVID isn't the death sentence many people at already low risk of dying from it fervidly believe it to be.

2. It undercuts the entire containment idea. (And I still think China realized this, said, "Oh, shit, now what do we do?" and shut everything down as the *only* way to effectively stop transmission between asymptomatic cases when contact tracing was too onerous.)
