Kotlin
Make JsonConfiguration itself @Serializable
What is your use-case and why do you need this feature? I would like to store the JsonConfiguration itself in a Json file and read them at startup. This allows to use different behavior with a simple change in the config files.
eg having a prod configuration and a debug configuration, which use a less strict Json De-/Encoder or uses pretty print.
Of course, the JsonConfiguration for reading the json configs must be static defined and cannot be defined in the config file.
Describe the solution you'd like Add @Serializable to JsonConfiguration
Current workaorund: Implement a custom serializer, which I did for my project
Closing for the reason described in https://github.com/Kotlin/kotlinx.serialization/pull/877#pullrequestreview-441582372
Its fine, my implementation was only adding 1 attribute :) But I would like to have the option changing the json behaviour with a config file, even with the new API.

Note that current JsonConfiguration is useless for creating new Json instances (as it was intended to be used mainly in encoders/decoders), so one still would need to use JsonBuilder for that.
