>  ConsumerInterceptor operates at batch level. There is no client-level hook for per-record processing lifecycle (span creation, MDC, context propagation). Frameworks and instrumentation libraries have independently built workarounds. It would be good to add a per-record lifecycle hook to fill that gap.
