Leaving aside the fact that I'm also comparing Rust... why not? It's a language that produces fast, static executables. I bet that a good fraction of the Debian archive (not all of it, for sure) could be reimplemented in Go without causing any problems. What "different universes" are these?

(To be fair, I haven't written any Go because my personal use cases involve things like shared libraries and C-ABI compatibility, so I'm going off what I've heard about Go, not personal experience. But out of what I've heard about Go, it's a fine language for this purpose, because the requirement here is just portability to all Debian architectures and comparable performance, and whether GC is used is an implementation detail.)
