The analogy is very sensible, but I would like to add that Kotlin isn't really hoardning features in the same way Scala did.
Compared to Scala, C++, or even Typescript and C#, Kotlin feels a like a well thought out minimal modern language (as minimal as you can be, while still providing conviniences that we have grown to expect like nullability checks, or data classes).
(*Except coroutines, I feel like Java is achieving that goal waaay better with virtual threads and structured concurrency than Kotlin did with "forever experimental" API that is full of footguns and lacks any observability.)
