Review comment:
Okay, I'll remove it. With regards to the JIRA issue filed from our
[conversation](https://github.com/apache/beam/pull/12352#discussion_r470939725)
about this, I'll move the TODO to where 'ParDo' is currently being prefixed for
other error messages
[here](https://github.com/apache/beam/blob/3e7371eae49b7aba142c8c0e898a62f583b49276/sdks/python/apache_beam/typehints/typecheck.py#L93).
