Yeah, it's important but not some grand law one should obey. I think every technical person has a time in their early life where they come across something that was genuinely wrong or illogical or just bad (in some cut and dry way). That imprints on them and from then on it is burned into our minds when we see something that seems off to immediately think "that is stupid". That is always my first (perhaps subconscious at times) thought I know and suspect it's fairly endemic.

All I take this nice parable to mean is that maybe you make your second, less instinctive thought be "why is that here?". That's it. Consider it then carry on. No law mandating a thorough investigation. No restriction on change without complete understanding. No need for deterministic certainty. Just a simple consideration that you should entertain. Or perhaps more accurately, a consideration you shouldn't disregard.
