Kotlin has this kind of switch as when from its initial version itself. Java is benchmarking good features from kotlin and introduced features like records, sealed classes etc.,.

It seems to me, a little bit poor style, create a switch with inner if, because you can create another switch with another if and so on. Let's use these feature in a wise way. It not that the feature is there we should use, in all cases, is good to know that exists.

Basically everything you will ever need to do in a real time project, you can do using Java 8 or Java 11 at most. Oracle made it mandatory to release a new update every 6 months, that's why there are so many Java versions. It's not practical to keep updating your source code to have the newest version when it's not even needed.
