    R: @tgroh this is only actually used by the direct runner. Not necessarily the greatest
JIRA for this, but I'm not sure of a blanket for cleaning out the SDK's excessive surface
area, so I went with the state ticket.

> Our current state API is targeted at runner implementers, not pipeline authors. As such
it has many capabilities that are not necessary nor desirable for simple use cases of stateful
ParDo (such as dynamic state tag creation). Implement a simple state intended for user access.
