You're not wrong, but I think there's a subtle way people still might get confused about `Vec` versus `Box` with the way you've phrased it. I'd argue the important characteristic of `Vec` here isn't that it's indirection but specifically that it's sized at compile time. Compared to a `Box`, it does not provide meaningful indirection around types that are themselves not sized at compile time (e.g. dyn trait objects), and storing them inside a `Vec` itself will require a `Box` or something similar.
