The Dos applications in production are probably delivered by floppy or CD. But hey absolutely with you, i "updated" a warehouse management machine ~7 years ago with FreeDOS and new Industrial-grade Hardware and automated email backup (haha take that cloud!), we had just one little problem with the infrared reader, but we found one with USB and DOS drivers and and everything was fine, so there's definitely a use-case for FreeDOS.
