Yes, there are plenty of non-functional logic bugs, e.g. performance issues. I think this starts to drastically hone in on the set of "all" bugs though, especially by doing things like network fault injection by default. This will trigger complex interactions between dependencies that are likely almost never tested.
They should clarify that this is focused on functional logic bugs though, I agree with that.
