You can upload a stream and monitor that for upload progress - so sure. If you upload a string for example you would have to take an extra step to get upload progress (make it into a stream and monitor that). There is additional (unrelated) talk in the fetch standard itself to provide this sort of functionality as part of `fetch` which would save the middle step.
