> Let's say your organization wants to add "dark mode" to your site. How does that happen? A site-wide feature usually requires several people to hash out the concerns and explore costs vs. benefits. Does the UI theming support dark mode already? Where will users go to toggle dark mode? What should the default be? If we change the background color we will need to swap the font colors. What about borders and dividers? What about images? What about the company blog, and the FAQ area, which look integrated but run on a different frontend? What about that third-party widget with a static white background?

Only one or two of those questions are actually related to programming. (Even though most developers wear multiple hats.) If an organization has the resources to have a six person meeting for adding dark mode, I'd sure hope at least one of them is a designer and knowledgeable on UX. Because most of those questions are ones that they should bring up and have an answer for.
