I don't see this intended to unseat JSON. But it can be helpful for local testing and debugging of Rust projects. I wouldn't really expect this for general purpose serialization because JSON is more standard and for inner-app communication you can use something more compact. I did actually use this in a project because it differentiates between nesting of Option. Particularly we were having some confusion of Some(None) and None and this helped our tests catch more issues. In production we used JSON. Serde makes it trivial for the same code to switch between formats.
