   How do we intend to offer opentelmetery vendors a way to propagate information across tasks via context_carriers?

   My open telemetry Distro leverages tracestate / baggage.

   The task span is created from the dag run context and not from the previous task context

   airflow/airflow-core/src/airflow/api_fastapi/execution_api/routes/task_instances.py

   Line 568 in 83edc67

   context=dr_ctx,

   Because the dag_run.context_carrier is not exposed at the task level, I have no way to inject or propagate info to downstream tasks.

   Ideally a task should be able to inject information into a context_carrier and have it be extracted for dependent tasks.
