Yes technically the Kafka matter is a secondary to the author's main point, which is understanding each problem first. So yeah I would not waltz in and say, "Oh, no need for details, obviously you need to standardize on RabbitMQ not Kafka," without a second thought, even though it's likely that's roughly where we're gonna end up.

But even then, I am not going to write a custom library when the drivers for either product are perfectly adequate. Standardization works best when standards are flexible, and trying to force my homemade library on every team is inflexible (usually it's just arrogance).
