+Fallback (StatsD). `StatsDCollector` is still selected by this value, but the
+stack in `docker/telemetry/` no longer receives it: using this path also requires
+re-adding the `statsd` receiver to `otel-collector-config.yaml` and uncommenting
+port 8125 in `docker-compose.yml`, otherwise the metrics go to a port nothing
+listens on. Note also that `StatsDCollector` applies `prefix` to the metric name
+while `OTelCollector` does not, so switching transports renames every series.
