React 18 data fetching network call cancellation

I understood from various discussions online that for Suspense for data fetching to work properly React needs to be more directly involved in the mechanics of fetching data from the network. How will that work in practice? Would it take care of XHR cancellation for example in case a Suspense subtree is no longer needed or changes props? What will it mean for using libraries like Axios? Can strategies like retry with exponential backoff still be implemented? HTTP caching behavior?
