Kiosk mode is actually not CrOS only. switches::kKioskMode is used on
browser_window_controller_private.mm

(Thanks for your question, I now know slightly more about kiosk mode)

   // Kiosk mode needs the whole screen.
   if (CommandLine::ForCurrentProcess()->HasSwitch(switches::kKioskMode))
     return false;

Shouldn't this depend upon the hostdesktype?

Perhaps so, in any case I should probably test more thoroughly with fullscreen
in desktop mode and see how much of this code is called from desktop mode.

   if (ash::switches::UseImmersiveFullscreenForAllWindows())
     return is_browser_fullscreen;
   else
     return is_browser_fullscreen && IsBrowserTypeNormal();
-#else
-  return false;
