Game dev / producer here. If they haven't tried it, they can't really comment on the potential value, can they? That's like devs in the early days of AI saying, "It sucks, it'll never be good."

One easy case -- it's great at debugging issues that include data in Unity scenes. It can quickly look at a snapshot of editor state / component configuration / serialized data and tell you, "oh, this gameObject's Vector3 pos value is wrong".

Not revolutionary on its own, but a great feature, and there are more.
