Some people don't and won't need 50+ producers/consumers for a long while, if ever. Rewriting the code at that point may be less costly than operating Kafka in the interim. Kafka is also has a higher potential for failure than sqlite.
Ofc, and not everybody needs or cares for all the features Kafka has. Then use another known and tested messaging system. Use NATS or ZMQ. Or any cloud native pubsub system
My main point is, I have zero interest in creating novel solutions to a solved problem. It just artificially increases the complexity of my work and the learning curve for contributors.
