Have you read the JEPs? The primitive/object split is being fixed and value classes are coming. The rest of your post really just seems like preferences, personally I do not like operator overloading (scala ptsd), and I don't see the value in < or : over extends and implements, we all type > 120 word per minute, and I think Goetz's plan for withers over records will solve the properties problem. The fact that an experienced developer has to transcompile Kotlin to Java to understand some parts of it also doesn't seem like a plus to me.
