Author here. I did think about creating a programming language specialized for serialization. Fortunately, using just C seems to be sufficient for building a POC. Another advantage for using C is it is easier to embed into other languages. OPIC is more library focused, which would benefit for integrating into other languages. Jai language seems to be a application (gaming) focused language, and the language abstraction makes developer faster to code is more important.
