Arguably much of the “infrastructure” and visual language for GUIs have evolved in the light background/dark text scenario, and “dark mode” has been pretty much improvised in the past couple of years.

I work mostly in the daylight and thus mostly in light color schemes for coding (doubly so when I’m forced to use glossy screens) but I get the appeal of not having a full white spotlight in your face when coding something in bed at 3AM. But: I’d rather most of my screen be dark (eg with terminals) but still have my editor viewport to be light-background, even if it means shrinking it.
