    Hi, I'd like to work on this. The section in core-concepts/tasks.rst relies on task_instance_heartbeat_sec, which nothing reads in Airflow 3 since the task-sdk supervisor sends heartbeats on its own. I'd remove it, or replace it with steps that kill the worker process mid-task if that's preferred.
