One thing the other blog post missed and this post misses too is that you don't need Kafka to use Debezium with Postgres. This gives you a pretty seamless onramp to event streaming tools as you scale.
Are you referring to using Debezium embedded as a library? If so, yes, it absolutely has its place; for instance, it's used by Flink CDC. There's pros and cons to either way of running Debezium. Seeing embedded Debezium a lot for in-app use cases, for instance cache invalidation. Going through Kafka allows for reply and setting up multiple independent consumers for the same change event stream.
