I agree with you, but understand the critique others used. The problem is standardization, if you need special hardware to do things you get fragmentation. For the people who rely on the other cartridges, those games are all standardized. The SNES had optional networking https://en.wikipedia.org/wiki/Satellaview https://en.wikipedia.org/wiki/Satellaview, and the PS2 also had an optional expansion bay https://en.wikipedia.org/wiki/PlayStation_2_Expansion_Bay https://en.wikipedia.org/wiki/PlayStation_2_Expansion_Bay that would limit all games from utilizing it, and also as a requirement it would prevent much adaption. Whats the point of developing on a device that needs lots of other parts that most people won't have? Its like selling a game system with no controllers and each controller can be used for only a few games (like eyefi). This is why I don't bother with seeing m.2 SSDs enhancing online gameplay for faster loading. You always wait for the weakest and slowest loading game and network to start.
