I am wondering a bit what the best way here is. Removing the method seems not ideal because as you said users might have used it with Serializers/Deserializers implementing Configurable. In the Kafka ecosystem there seem to be different ways of configuring a Serializer/Deserializer one is the current one with implementing Configurable and the other is through the Serializer/Deserializer itself [1]. I am no Kafka expert so I don't know the right way to configure them. I guess we can also support both methods.
