Review Comment:
> Making it implicit should not be backwards incompatible, as otherwise the
pipeline wouldn't run, right?
The pipeline will just try to run in batch mode, which is actually probably
fine for some unbounded sources (I think). It will run in batch mode, but
generally functions fine AFAIK.
With that said, I don't really fully remember what our concerns with opting
in to streaming first mode are. There are use cases here
([example](https://lists.apache.org/thread/p9g47xfowygjdrjjwo2f62hfjdjy70s7)),
though they're pretty dubious IMO.
> I don't recall. What's the behavior in other SDKs?
Other SDKs opt in any unbounded sources to streaming pipelines.
