(Note that the Rust implementation is by Facebook, not by Google.)

If you're looking to embed a scripting language in a Go program, having a embedded language implementation written in Java isn't very useful. And vice versa.

Yep. Basically the same reason there are so many lua implementations, or WASM ones.
