Well, keep in mind that Go also predates Docker by a bit. Docker really did solve the whole dependency issue of dynamic languages/runtimes, but Go still has a possible advantage here - it can be built in a much smaller container..even SCRATCH. A minor convenience at best, but something.
It's a very odd state of affairs. In an age of docker, nix uberjars, ever more sophisticated user and system space filesystems it's really questionable what value they bring.
People say, "Simplicity" then they bling out their docker containers with multiple layers of processes and initialization anyways.
Go's tooling would have been great in a pre-Docker era. Now... I don't see the appeal.
