Well at least Nintendo themselves still releases full game cartridges and it’s not like you buy a Switch for third party games anyway. Nintendo only introduced the Gamekey card because third party publishers, especially Acti and Ubi, were releasing their own version on Switch 1 and not using consistent packaging labels to tell a gamekey from a full game cartridge apart so probably confused many consumers. Hence why Nintendo created an official version.
A lot of Switch cartridges now only have license keys.
