kotlinlang

I have an question regarding the new "value class" (successor of "inline class") from 1.4.30: it states: "From now on, Kotlin requires the `@JvmInline` annotation before a class declaration for the JVM backend".  Is that only required for Java compatibility or do I have to add this to all value/inline classes going forward for all my JVM code, even for 100% Kotlin code?

I believe it required if you target JVM, it will not compile JVM artifact without it (at least until you target it to valhalla, which is not supported yet)
