Comment (by joyously):

 I happen to have authored a theme where the user can choose whatever color
 they want, so my theme would have a difficult time with dark mode or your
 proposed theme_support field. It also allows the user to easily swap
 foreground and background on various elements like sidebar or widgets (or
 wherever they put the class). So even if I do analyze the background color
 to determine dark or light, they could have swapped it on `#main` or
 `#content` and so the analysis is moot. Adding an inaccurate body class
 won't solve your problem, and it should work without the theme having to
 do anything or it will be forever until adopted.

 If your concern is about things like `<select>` being the "correct" color,
 it seems that you have tested with themes that don't style everything. My
 theme styles `<select>`, and it all matched until a recent update to
 Firefox that made my styles not work.
