Or you could look at the link, and see that you're talking out of your ass. For whatever reason Apple's display controllers are huge - bigger than multiple cores - and clearly there isn't random left over space on the die for another one without sacrificing something else. I get many people on HN hate the idea of Apple existing as a company, but it turns out it is possible for things to not be "Apple is evil, and everything that they do is malicious". Something like the studio supports multiple displays because - afaict - it's multiple complete SoCs glued together, so presumably also has the display controllers from each complete SoC it has.
