Beam documentation inconsistent

Apache beam documentation is inconsistent about Python usage of Pub/Sub.  The chart [here|https://beam.apache.org/documentation/io/built-in/] claims that Pub/Sub is available for usage in Batch Pipelines, but the source [from clicking on that link|https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/gcp/pubsub.py] explicitly says only streaming is supported.  Both of these cannot be correct.
