Your word of caution is important. For some projects it's not initially clear what the right data model and bounded contexts are. And for some projects it's just overhead. But the converse is also true: for some projects/systems it turns out that it being events first is the _only_ way for it to work. I've encountered that the last few years with systems in logistics that show an integral view across parties.

The way we approached that is that we started with a standard system and refactored to event processing approach when the decomposition into bounded contexts was clear.

So in that sense it's similar to the right way of approaching microservices: start out with a 'monolith' that you split up.
