For a trivial issue like the one the article covers, sure. But often decisions have larger impact. The cost of a bad decision can be higher than the cost of fighting for the right decision. If Kara weren’t just designing a single new icon but electing to, say, replace nearly the entire suite of icons with flat iconography, that’s a pretty impactful decision. This significantly impacts the design choices that other designers will have to make. Domain expertise is not always unique to the other person, either. When negotiating with a coworker on a design or feature request, it’s entirely possible that the person asking for the change has more domain expertise than the person empowered to make the choice.
