Also, in the case when InnerWrapper is lazy-loaded, it going to be fetched after OuterWrapper is rendered. So, in this case, both components aren't fetched in parallel but one ...
The only use for Suspense is to allow showing some fallback while React loads a lazy component. For other types of lazy loading app data you can implement your own fallback, as in: const SuspensefulUserProfile = ({ userId }) => {. const [data, setData] = useState(); useEffect(() => {. fetchUserProfile(userId).then(setData);

And will render the fallback while the data promise is not resolved. The only issue is that you can't pass directly a promise, but you need a wrapper that transforms it into a ...
