Question: Will this packages support `extension types` like `kotlinx.serialization`? #1405

Kotlin's JSON serialization library(kotlinx.serialization) supports the value class in the following way:

Code:

@Serializable
@JvmInline
value class Color(val rgb: Int)

@Serializable
data class NamedColor(val color: Color, val name: String)

fun main() {
  println(Json.encodeToString(NamedColor(Color(0), "black")))
}

Json:

{"color": 0, "name": "black"}

I'm wondering if this package will support Json serialization in a similar way to Kotlin.
