These details (the function to setup tracing, the addresses to which traces are sent, and the `TRACING_SAMPLING_PROBABILITY` variable) are stable for 7.x, but other details of tracing, such as the instrumention and the tags that are sent, are subject to changes even within 7.x.
+In addition, tracing relies on a specific version of the `opentelemetry` modules; you can find a complete list of dependencies that work in `samples/go.mod`.
