If ActorPublisher/Subscriber are to be deprecated what is the recommend approach?

[acds]

Per:
https://getakka.net/articles/streams/integration.html#implementing-reactive-streams-publisher-or-subscriber

WARNING
ActorPublisher class and ActorSubscriber class will probably be deprecated in future versions of Akka.

What is the recommended approach?

One tends to want to wrap a source resource up in an Actor (say to call a REST API that returns batches of results) and pipe those results into a stream, but have back pressure to only get the next batch when down steam can handle them.

The WebCrawler sample uses the Actor as a Coordinator but then you lose out on the Actor wrapping the source on its own so you break your API encapsulation.

Also much of the documentation related to article that is linked in issues related to Streams, or on the Petabridge site seem to be broken.

Thanks for any insights.
