Debugging complex systems in production is much easier, if you can rely on certain things. Thus, simple logging to files using known configuration eliminates one variable to debug. With an event bus, there’s always the question of “did the event not happen or did some upfckery prevent the message from getting where I can see it?”. While I do agree with the need to simplify code, moving to an event bus transfers the complexity to where we don’t necessarily want it - to system level. Now there’s one more moving thing to be deployed, monitored, scaled, networked. And, by the way, that moving thing is mission critical, as without it you are flying blind, including in terms of infosec. Is it worth it? Maybe in some scenarios. But definitely not to the level of a code smell, that should be something to be avoided universally.
