To be able to use WASM-compiled languages for embedding you first need a small WASM runtime you can depend on (and things like ref types, GC etc which have been standardized only in the last couple of years).

That didn't exist until recently, but now you can use https://github.com/bytecodealliance/wasm-micro-runtime/blob/...

I am not aware of anyone using this yet, but I hope to see that become common in the next few years.
