I’m going to shove email-sending (TaskInstance._email_alert) here too. The error emails require a task context, which is most available in the runner, so it should probably be done together with the task callbacks.

So we need to handle

1. task-level callbacks

   airflow/task-sdk/src/airflow/sdk/definitions/baseoperator.py

   Lines 1039 to 1046 in df584d3

   	# TODO:
   	# self.on_execute_callback = on_execute_callback
   	# self.on_failure_callback = on_failure_callback
   	# self.on_success_callback = on_success_callback
   	# self.on_retry_callback = on_retry_callback
   	# self.on_skipped_callback = on_skipped_callback
   	# self._pre_execute_hook = pre_execute
   	# self._post_execute_hook = post_execute

2. Notifiers (see top message)
3. Email sending.
