Tree Example Clarification

[daninus14]

The Tree example https://atlassian.design/components/pragmatic-drag-and-drop/examples/#tree

Has this sandbox https://codesandbox.io/p/sandbox/nqhc6t?file=%2Fexample.tsx%3A65%2C1-66%2C1

The main function is named TreeLegacy even though it uses @atlaskit/pragmatic-drag-and-drop-hitbox/list-item instead of tree-item as mentioned in the docs: https://atlassian.design/components/pragmatic-drag-and-drop/optional-packages/hitbox/about#tree-item

What makes it legacy?

What is the current recommended approach?

I thought tree-item was depreciated as mentioned in the docs: https://atlassian.design/components/pragmatic-drag-and-drop/optional-packages/react-drop-indicator/about . But in the tree example it works with tree-item not list-item. So are we supposed to use tree-items or not?
