I think aggregate tracking is interesting because it can be informative without violating privacy. For example, for a sales or pitch deck it might be interesting to see if certain slides captures a lot of attention or don't resonate at all. But I don't like individual tracking where it feels like someone is looking over my shoulder while I view a deck. I don't like that Superhuman did that kind of tracking by default, either.
