I think default methods take care of most of the places where boilerplate would be required. The abstract collections are a great example of this; most of the methods required of a `Collection` can be implemented from a small subset. Sometimes you'll re-implement other operations anyway for efficiency gains, but that's supported with default methods also. However, I may just be weird. My Java coding style is probably closer to Rust or Haskell. Lots of interfaces defining my type requirements, and static methods to implement compound operations on those interfaces. I like this because it's easily testable and traceable.
