https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/autoconfigure/src/main/java/io/opentelemetry/sdk/autoconfigure/AutoConfiguredOpenTelemetrySdkBuilder.java#L449-L456 is called even if declarative config is used.

The result of the call is discarded, except

• that a properties customizer may set otel.experimental.config.file - but that's not a valid use case IMO
• for side-effects - and that's a bug rather than a feature IMO
