UX/a11y is a specialized skill, which might look easy to pick up from the outside, or is dismissed as “soft” by hardcore C hackers, but if you don’t think deeply about it or listen to those that know their shit, you get situations where the color of the clock in the dock is almost indistinguishable from the background (yes this has happened to me, and no, I don’t want to learn how to fix it), or how you can literally lose image information because “user choice” (==being able to reorder modules just they way you like them) is seen as more important than enforcing correct usage.
