- Fetch streams are not ideal for measuring upload/download progress due to inaccuracies.
- Response streams allow processing data chunk-by-chunk but struggle with compressed content.
- Request streams enable parallel processing and uploading but are unreliable for progress tracking.
- Using streams for progress measurement may limit future browser optimizations.
- XHR remains the best current method for accurate upload/download progress events.
- A future Fetch API proposal aims to include progress events for both uploads and downloads.
