I don't think its unreasonable to just add a date next to the serial number that has when the firmware was released. It's 6 extra numbers

But firmware can be updated after the unit was shipped; a date stamped on the hardware can't promise accuracy.

It's 8 extra numbers

FTFY, unless you use the YYYY-WW date format. But please don't use just two digits for year numbers, we should have learn from Y2K years ago.
