This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!

@krystofwoldrich with https://github.com/getsentry/sentry-javascript/issues/8510 done, what's missing here?

[krystofwoldrich]

The JS Core Integrations are now sending the trace origin, the RN Integrations are still todo.
