It's a comparatively minor problem, sure. It's also downright trivial to fix, as all that takes is removing Thieves Cant, sticking it on a background somewhere, and calling it a day. That immediately broadens what the rogue class can represent, and it provides options for everyone else to get Thieves' Cant - say you have a thug who works for someone in the criminal underworld, as muscle. This is someone who fits in the Fighter class, but really has no excuse not to know Thieves' Cant.
