How hard would it be to have @Serializable(with = ...) work at the top level

@Serializer(forClass = CustomData::class)
class CustomDataSerializer : KSerializer<CustomData> {...
}

@Serializable(with = CustomDataSerializer::class)
data class CustomData(val data: String)

fun m() {
  val x: KSerializer<CustomData> = CustomData.serializer() // this doesn't compile
}
