I'll add the tests and codemod once I have a confirmation that we agree to go with this new API.
We discussed it a few weeks ago in a meeting.

And I'd also like to confirm if I should apply the same renames to the selection API (defaultSelected => defaultSelectNodes, selected => selectedNodes, onNodeSelect => onSelectedNodesChange + create a new onNodeSelectionToggle).
For me it makes a lot of sense to at least do the renaming. For the new onNodeSelectionToggle we can wait for users request but I'm pretty sure it's something we want to add so maybe it's better to just stay consistent with the expansion and add it now.

Looking good ... you just missed a change to the jsdocs. Other than that I only have 2 small comments on the wording. Very nice!

Nice improvement! 🎉 The renaming makes sense to me 👍
For consistency's sake I would rename the selection api as well 🤔
