Hm... There would suddenly no longer be a difference between HasChildren::find() and HasChildren::findPageOrDraft() anymore, right? I feel like there could be use cases where one would want to explicitly only find published pages. So this would be a breaking change and also one that wouldn't be intended I think.

Maybe we need to introduce a separate recursive finding mode that uses childrenAndDrafts(). That could then be specifically used by HasChildren::findPageOrDraft(), also allowing us to get rid of the separate search in both collections.

One way could be to have a new marker prop for Pages that keeps track of whether the collection is children, drafts or childrenAndDrafts. The same collection type would then be used in the findByKeyRecursive() method.
