I've seen this kind of thing done on PCBs as well. Stick a useless component somewhere that does nothing (like a resistor with its terminals shorted together), and when you find a clone with your exact layout and your extra component there, then you can be sure it was straight up copypasted.
- Cartographers will do this with small non-existent roads, too. They're called "trap streets"!
