## Motivation These are incorrect: currently, when you have a `None` layer, the `None` hint it returns causes the default `TRACE` to win, which is inaccurate. Similarly, `Vec` should default to `OFF` if it has no `Layer`s in it ## Solution Change the default hints to `Some(OFF)` Co-authored-by: Eliza Weisman <eliza@buoyant.io>
