so, okay, we've been making mistakes in production with DNS since we were 16, right? we can tell you some stories!
none of them end in someone telling us "don't worry, nobody else understands the changes they make when they do this either".
hearing this from someone well-regarded in our field would have been actively detrimental to getting us to where we are today.
because we guarantee you that for every do-ho-ho bumbling mediocre guy who goes "lol, nobody understands $thing" there is at least one person who does, cleaning up after the messes that this type of fucking guy leaves behind.
