"""
This module provides functions for safely retrieving and handling OpenLineage configurations.

For the legacy boolean env variables `OPENLINEAGE_AIRFLOW_DISABLE_SOURCE_CODE` and `OPENLINEAGE_DISABLED`,
any string not equal to "true", "1", or "t" should be treated as False, to maintain backward compatibility.
Support for legacy variables will be removed in Airflow 3.
