All these steps could be condensed to:

cp build/llhttp/wasm/* <path-to-undici>/lib/llhttp

If we remove the embedding and use the llhttp project build. Just wanted to say that's an option if this is too clumsy.

This guide should be revisited if/when we have to modify lhttp sources for whatever reason.

Can we avoid embedding as of now?

Yes, we can. We don't currently modify the source files. IMHO is a cleaner approach, as long as we don't have to customize it. One thing to consider is the direction the llhttp project will take towards wasm. For example, what if the only way to access the build would be by installing it as a dependency and use its .js API (as suggested in nodejs/llhttp#93)? Would we be open to that?

But regarding now, we would just have to run build-wasm in llhttp and copy the build/wasm folder contents in lib/llhttp.
