Having explored that approach (†), I can tell that generating Go assembly is harder than it seems.
reply†: I've tried to transpile Rust code through WASM into Go assembly, and I've also explored how to inject trampolines into Go binaries (which involves generating Go assembly too).
That is interesting, but I imagine Rust has features which can not be translated into Go's assembly. This language is specifically designed for Go interop; the logistics wouldn't be the same, though I still expect it to be difficult.

replyWhy would there be? Go’s assembly might be lacking ways to make them optimally efficient, but that’s probably a given either way without an optimizing compiler backend.
