Are there any plans for union types in Kotlin or at least KotlinJS? I heard mentions in one if the arrow meta talks that kotlin already supports union types, just doesn't expose them to public api. Curious to know why

You might be interested in #CJ699L62W, they have a compiler plugin that adds support for union types. They're waiting for the IR backend to be stable so it can be fully released.
