> Streams does not allow to overwrite some config parameters (eg, {{enable.auto.commit}}).
> Currently, those checks are done when the consumer/producer config is generated, ie, when the consumer/producer in instantiated. This means, the check is done quite later after {{KafkaStreams#start()}} was called.
> It would be a better user experience, to check user provided configs early on, ie, in the constructor of {{StreamsConfig}}.
