I'd encourage you to take another look at the article because I don't think your criticisms are well founded. The javascript version does exist! The fact that it's produced by a compiler doesn't undermine it's existence.

Well written and useful article if you would like to learn about what type of optimizations are effective in targeting the wasmgc runtime.
