I personally don't see what would be wrong with reproduction cartridges. After all, I can't imagine too many original ones still being properly functional after all these years. All a reproduction cartridge is is slapping the same game data into a more recent cartridge anyway. Also great for rom hacks that decided to go the extra mile of making an official cartridge release.
Now if it's just a collector's pet peeve because everything needs to be 100% old and 100% not-reproduced, then it's a very minor complaint that only affects their collecting fix, and not the ability to play the games. All GameStop needs to care about is that they're functional, not that they're vintage.
