+  various pluggable backends.
+  ([#3752](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3752))
+  ([#3759](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3752))
+  ([#3763](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3763))
 - Add a utility to parse the `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT` environment variable.
   Add `gen_ai_latest_experimental` as a new value to the Sem Conv stability flag ([#3716](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3716)).
