The reason is indeed mass production. It would actually be more expensive for the manufacturer to provide a q/r link, and greater liability as well. Do NOT punch out and reinstall pins on any chain that is designed for above 6 cogs in the rear, and even those that are for 5/6 only may have construction that makes reusing the pin unwise.
