WebAssembly support isn't sufficient on its own. You also have to deal with various WebAssembly features, such as thread support and growable heaps, that are relevant to your app. There are more features coming to WebAssembly in the browser, including hopefully a way to feature detect in the WebAssembly binary instead of the way it's done now, which is to compile as many binaries as you need for combinations of features, feature test in JS, and then pick which wasm module to load.
