With kotlinx-serialization, I want to be able to annotate a property as `@Ref` and have the serializer _only_ serialize the `id` property of the referenced type. Is this possible? I.e.

```data class Video(
    val name: String,
    @Ref val user: User,
)

// serialized to:

{
    name: "example",
    user: {
        id: "123"
    }
}```

I'm not sure how you expect deserialization to work, but…

If you don’t necessary need JSON - I wrote a library that serializes/deseeializes to binary with Amazon IoN that retains object references.
