Review comment:
I think having a single "backwards compatibility" parameter can be confusing
and error prone. We might still be backwards incompatible in some unknown ways.
I think it's better to document exact differences between the transforms and
give clear documentation/guidelines for anyone who is upgrading.

> The proposed BigQuery bounded source in Python SDK (see PR:
> [https://github.com/apache/beam/pull/9772)] uses a BigQuery export job to
> take a snapshot of the table and read from each produced JSON file. A
> performance improvement can be gain by switching to AVRO instead.
