Friction-less scala - Tell us what is causing friction in your day-to-day life with Scala

One way I've solved this is to use Protobuf contracts to serialize json with ScalaPB. They have a way implementing oneof that keeps each object individual and separate. Even if you don't decide to use PB, you can take some inspiration from the implementation.
Scala 3.0 serialization

You could try out protocol buffers. Not sure how stable it is, but I noticed they have a Scala3 version of their runtime library. (Disclaimer: I have not tried it out myself)
What are some alternatives?
ScalaBuff - the scala protocol buffers (protobuf) compiler
Scrooge - A Thrift parser/generator
µPickle - uPickle: a simple, fast, dependency-free JSON & Binary (MessagePack) serialization library for Scala
scodec - Scala combinator library for working with binary data
Avro4s - Avro schema generation and serialization / deserialization for Scala
Chill - Scala extensions for the Kryo serialization library
cats-effect - The pure asynchronous runtime for Scala
