There has to be more to it than that, right? I'm no software developer, but I can't imagine a feature request with 700+ votes and 2+ years old has simply been ignored when it could have been done in a few hours. FWIW, I tried that Stylish addon and had poor results. Yes, I got dark mode, but sometimes I got dark text on a dark background.
