I don't understand this line of reasoning. WebAssembly isn't 'sandboxed native code', it's a compressed AST, and even if it was native code there's nothing stopping someone creating a native compiler for TypeScript. That said, Typescript is most likely to support WebAssembly when WebAssembly offers a GC implementation for it to use (the WebAssembly GC is planned in the medium to long term IIRC).
