> Thankfully, there is the esm-integration proposal, which is already implemented in bundlers today and which we are actively implementing in Firefox.

From the code sample, it looks like this proposal also lets you load WASM code synchronously. If so, that would address one issue I've run into when trying to replace JS code with WASM: the ability to load and run code synchronously, during page load. Currently WASM code can only be loaded async.

This is not strictly true; there are synchronous APIs for compiling Wasm (`new WebAssembly.Module()` and `new WebAssembly.Instance()`) and you can directly embed the bytecode in your source file using a typed array or base64-encoded string. Of course, this is not as pleasant as simply importing a module :)
