That would be my dream. Another comment highlights that Go's memory management may not be a good fit for WasmGC, so we may not get near-native performance, which would be a bummer.
While I look forward to being able to use things other than Javascript or languages seriously confined to Javascript's basic semantics in the frontend, I expect Go to be a laggard because it's going to be hard to get it to not generate relatively large "executables". I expect other languages to be the "winners" in the not-JS-frontend race.
