Hm, I found that it works if I use

@InternalSerializationApi
override val descriptor = buildSerialDescriptor("...", CONTEXTUAL)

but I don't like the internal serialization api being used.
It's documentation says that it should not be used, and if necessary issues filed.
So is there another way to get a serial descriptor with CONTEXTUAL kind?
