Rust (the language the Xi core is developed in) has static typing for JSON, as well as other serialization formats: https://github.com/serde-rs/json

I'm familiar with serde. It's an incredible project, but I wouldn't quite call it "static typing for JSON". You still have to unwrap the parse at some point. However, I will concede the point that if you have Rust on both sides then you'll get most of the benefits.
