Nixpkgs go stuff complained about the nested module in nix/nixos/test/socket-server, which is not a problem for go build.

If I'm not mistaken the command needs to point to a mutable location so that on reload, it would load the new command.
As an aside, the command script might also include a bunch of env vars.

I figured this could be covered by an entry in a config file instead. Not dissimilar to a systemd unit file, but far more limited, because we can't change many of those fancy settings like security or mounts related ones once the systemd service is running.
