Hi Adam, Thanks a lot for sharing this. I'm positive this will be useful for quite a few people on this list.
We're currently not investing too much in this area ourselves, as the alternatives are much more compelling. E.g. using Kotlin or other languages, or waiting until we finally have java.lang.Record. I have high hopes for the impact of the latter on our ecosystem. The closest we can offer is the <fluentSetters/> code generation configuration flag (which works for mutable POJOs). Of course, writing your own generator is a viable solution here as well. I don't think there's anything wrong with this approach - I've recommended it numerous times in the past.
