If you want to see LOADED modes derived from prog-mode you can do
this sort of thing:

 (cl-loop for sym being the symbols
          if (provided-mode-derived-p sym 'prog-mode)
          collect sym)

I imagine Gregory grepped the codebase for define-derived-mode
definitions deriving from prog-mode, though, rather than loading
all of the things.
