I suspect as time goes on we'll see more and more of this become direct through optimization. My understanding is that this already happens for certain well-known methods, like if you import Math.sin or something V8 is going to optimize it to a direct call when it compiles the Wasm module that imports it. And maybe a non-JS interface will emerge, but there needs to be some kind of layer that preserves capability security. You wouldn't want any and every Wasm module to have access to the entire browser API. You will still want the ability to omit capabilities, attenuate them, etc. and for that a full programming language seems necessary and well... JS is already there.
