Differences between node.toJSON() and getSnapshot(node)

[NgoKnows]

In the documentation here: https://mobx-state-tree.js.org/tips/more-tips#tojson-for-debugging, it describes .toJSON() and getSnapshot as equivalent, but it appears as this is only true for models?

For example, for observable arrays, calling .toJSON() on an observable array, only converts it shallowly, but for models, this is not the case.

Here is an example (it is better to see the logs in the actual browser console so you can see which are plain objects and which are still MST nodes):
