I would argue that if your unit test is only testing things which would have been shown by the type system of another language, you are testing at too low of a level. In addition to being tedious, such tests are often very brittle.

Those tests are brittle, and they're also the thing that protects you at module boundaries when those boundaries are being hammered on by different groups of people.

Having them not be necessary is nice.
