I know this article uses Rust but if you look closer at Lunatic project its about WASM not just Rust so in future it can support any language that compiles down to WASM. If you go to Lunatic GitHub repo first things written there is this "It is heavily inspired by Erlang and can be targeted from any language that can compile to WebAssembly. Currently there are only bindings for Rust available.".
I also find this project very interesting and maybe in future it can be alternative to Erlang VM.

You are right, I missed the "forest for the trees" :)
