> This source includes a lot of assumptions & assertions that may cause problems on
runners that implement UnboundedSources differently. For example:
> 1. It requires that finalizeCheckpoint is called at most once.
> 2. It requires that the checkpoint be finalized within the pubsub timeout, or the messages
will be redelivered.
> ... (possibly other assumptions) ...
