Very well said. This is basically what I picture when I think of "mature organizations". You strive to never touch things in production except to restart them or deploy a different version. When you find yourself wishing you had some debug utility, that's certainly a sign that you need better observability. Rolling out a new release with your improved instrumentation isn't a good fit for an urgent problem, but these cases become increasingly rare over time as your observability improves and moreover you can always deploy a "debug" version of your application with various debug utilities compiled in).
