For React 19 users this might be a good fit: https://www.notion.so/sentry/React-JS-19-23a7a2c5f88d4ef59a4b9647c84333a3

With that they could disable their inbound filter and start consuming error-quota and get hydration-errors. These would include useful stack-traces. If the React19 user also has replays installed, then they'd get replays attached.
