Description
We've observed some regressions in internal pipelines. We've narrowed the root cause down to [https://github.com/apache/beam/pull/17384](https://github.com/apache/beam/pull/17384) - the worker changes for Batched DoFns.
I still don't understand the root cause, but given this change can lead to a regression in pipelines that don't use the feature I think we should roll it back.
Imported from Jira [BEAM-14481](https://issues.apache.org/jira/browse/BEAM-14481). Original Jira may contain additional context.
