Are there any plans on supporting polymorphic serialization of sealed interfaces?

It's supported, unless you mean automatically.

I mean automatically.. e.g. I would like to be able to have this:

@Serializable
sealed interface Animal { val name: String }

@Serializable
class Cat(override val name: String): Animal

@Serializable
class Dog(override val name: String): Animal

Currently it works great if you use sealed class , but an interface feels cleaner when we only have abstract properties

Also, with an interface it is possible to reuse classes in multiple hierarchies.
