It can be a problem if you care about schema compatibility for your events - and I would care about it in a multi-team microservices setup. Your database schema essentially becomes a contract, your service is not a "black box" anymore. You have locked yourself from the ability to change the schema freely.

Also, the messages produced reflect database changes, not domain events. I would prefer to have an explicitly defined interface layer for consumption. At least, use database views as contracts with Kafka Connect.
