Can I use a ZSink to commit offsets in Zio-Kafka?

Question

I am learning ZIO integration with Apache Kafka, using the library zio-kafka. In the example on the Github main project page, they use a mapM function to commit the offset of a chunk:

Consumer.subscribeAnd(Subscription.topics("topic150"))
  .plainStream(Serde.string, Serde.string)
  .tap(cr => putStrLn(s"key: ${cr.record.key}, value: ${cr.record.value}"))
  .map(_.offset)
  .aggregateAsync(Consumer.offsetBatches)
  .mapM(_.commit)
  .runDrain

However, IMHO, committing the offset is a terminal operation on the stream. Which is the difference in using a ZSink, instead?

Consumer.subscribeAnd(Subscription.topics("topic150"))
  .plainStream(Serde.string, Serde.string)
  .tap(cr => putStrLn(s"key: ${cr.record.key}, value: ${cr.record.value}"))
  .map(_.offset)
  .aggregateAsync(Consumer.offsetBatches)
  .run(ZSink.foreach(_.commit))
