What is the status of "shallow renderer"?

Google leads me to this page: https://reactjs.org/docs/shallow-renderer.html
However, I can not find it anywhere in the table of contents on the right.
Note that the versioning on the page suggests that this is a feature of React 18

I see that react-test-renderer does export react-test-renderer/shallow ( https://github.com/facebook/react/blob/main/packages/react-test-renderer/shallow.js ), but it isn't documented (https://reactjs.org/docs/test-renderer.html). I also see that shallow-renderer ( https://www.npmjs.com/package/react-shallow-renderer ) is versioned 16, and was last updated 2 years ago, suggesting to me that it is not up to date with React 18.

It would be nice if some clarification of the state of this feature was added to the page. (I'd be happy to volunteer to make such a PR, but I have no way of knowing what the definitive answer is :-) )

Comienza con la página de documentación enlazada de shallow renderer y el punto de entrada react-test-renderer/shallow.js; después, compáralos con la documentación enlazada de test renderer. Determina el estado de la funcionalidad en React 18 y si el paquete separado react-shallow-renderer está actualizado. Se considera terminado cuando la documentación indica claramente su estado y aparece adecuadamente en la navegación.
