It's the rebirth of Java without the drawback of necessarily needing a runtime; write once in whatever (supported) language and run everywhere, if other platforms like OSes embrace the standard. The closest thing I've found is Flutter but that's only in Dart.

Another use case, imagine a single program mixing and matching many different languages because they all compile up WASM as a universal format. This already happens in the frontend web with so called microfrontends which basically let you write various components in React, Vue, Angular etc and it all compiles down to JS.

Or more like CLR/.NET (and even Java/JVM with the proliferation of JVM languages) where you've got a bunch of languages targetting the same VM.
