> Datastore has a few classic Dataflow templates that rely on being able to provide all parameters at runtime.
> The newly introduced `hintNumWorkers` parameter needs to be switched to a `ValueProvider` to make that compatible for adjusting parameters. In addition, the `firstInstant` object should not be serialized into the template itself, as that freezes the start point for weeks at a time.
