I think there are a lot more when I search for unwrap in the repo. At the time, I think my intention was that we would just use at least expect in place of unwrap. We use unwrap in a lot of our unittests so finding them will be a bit tedious. Fortunately, any that are in tests are most certainly at the bottom of the file so it should be easier to find.

There is also the case where some of the unwraps are acceptable to unwrap but use your best judgement:
