This is spot on. One interesting approach I've seen before is that all commands executed as the superuser must be written in file, and the only command accessible via sudo is "please_save_to_audit_log_then_run_it_in_sandboxed_env <file>". For particularly high-risk situations, there might be a second person reading your script before running an approval command that actually lets the script run. Things don't move quickly, but the number of mistakes via typo is certainly reduced.
