I think this has something to do with how PD has always valued the aesthetic side of things, just like having generic slits on tyres when you put racing slicks on historic cars. Yes, having those barcode-looking substitutes is gonna make it look more period-correct, but having them on the car will displease some people because it simply doesn’t look nice to them. Removing them will also make other groups annoyed, but given they don’t know how many people find these things important, they probably just went with what they thought looks the best. Either that or
it simply wasn’t on the car when they modelled it for the game.
Anyway, it’s one of those small decisions that I welcome.
