It is the latter. It will impact users of Specific IO (BigQueryIO read) specific configuration (Direct_Read). Note that the default configuration for BigQueryIO read is EXPORT. So this won't affect "quick-start" examples having default settings. It also won't affect users using SDK docker containers (e.g. Dataflow users and Flink/Spark users running on a remote cluster). It will affect users running in direct runner, and local portable runners (e.g. Flink local cluster) with LOOPBACK configuration, which is exactly what our Python PostComit is doing.
