But relevant to what? Some things are relevant directly to the outcome by nature of what you're trying to express, while some other things are essentially incantations you need to repeat the same every time. Bad build systems and what you have to do to make them work are definitely relevant towards building a working program when you're using them, but at the same time the specific details are often somewhat irrelevant for your goal.

Also, many stupid or nonsensical statements can often yield wisdom if you meditate on them enough. Indeed, many (most?) zen koans are so simplistic that to get any usefulness out of them you have to insert you own assumptions and try to determine how it might apply.

Relevant to the problem you’re trying to solve. If it’s only relevant to what you’re using for solving it (i.e. choosing a different tool would have make those issues disappear), then that make them irrelevant.

Each tooling set will bring its own irrelevant details. But you can rank them according to the amount and complexity of the irrelevant of details you have to think about.
