Hi, any news on this?

Not for this specific sample, but https://github.com/temporalio/samples-ruby/tree/main/context_propagation is available that shows another use of interceptors (setting/retrieving context values via headers). Feel free to join us on the #ruby-sdk channel in Slack or in the forum if you need help building interceptors.
