May be dumb question but

Why is this fine

@Serializable
abstract class Abstract(private val prop : Int? = null)

@Serializable
class Impl(val property: Int) : Abstract(property)

But this is Impossible to make this class serializable because its parent is not serializable and does not have exactly one constructor without parameters for Impl class

@Serializable(with = SomeSerializer::class)
abstract class Abstract(private val prop : Int? = null)

@Serializable
class Impl(val property: Int) : Abstract(property)
