...okay, I can let this nonsense go today with very little impact, but if I do... will the team need to deal with it 100 times in the future? (And more broadly, by silence am I contributing to the evolution of a bad engineering culture ruled by poor understandings?)
It is very very difficult to know where to draw the line.
Three axes in my mind to take into account: Likelihood, impact, and complexity. The article seems to mostly be about likelihood and complexity. I'd place more importance on impact and complexity. It's worth saving a headache later if it's simple to do right now, however unlikely it is, as long as it doesn't create a maintenance burden before that point.
