Adding Apple CarPlay and Android Auto (if Tesla does one, they would have to do both - due to the 50-50 market split between the two OS) would likely be considerably more complicated than adding games.
The games only run while the vehicle is parked - so those apps can be implemented without worrying about interference with other operations - essentially the MCU is in "offline mode" while the games are running - a much simpler environment.
Adding the Apple and Android screen mirroring systems would be more complicated, since they would need to run while the MCU is also busy with everything else that runs while the vehicle is in motion - including the Tesla user interface, map display, navigation display, ...
In the past, Musk has indicated they would likely go a different route - either implementing their own screen mirroring or using a 3rd party solution - and not go with the Apple or Android solutions.
Addressing smartphone integration is long overdue for Tesla - along with fixing the long standing bugs and design flaws in the software. The voice command system could do much more, reducing touchscreen interactions while the vehicle is in motion.
However, Tesla (Musk) is still moving full speed ahead on implementing FSD - and if they believe they are within 12 to 24 months of really getting FSD working, that makes it more likely Tesla will focus more on functionality that would be more useful while the vehicle is in FSD mode, such as increased entertainment options for the passengers, and less focus on minimizing driver disruptions (since the human driver would become a passenger).
