I also think Apple's secrecy works better than one might assume. Yes, we get a lot of leaks, but those are typically from the supply chain: by and large, they're hardware leaks happening in East Asia, not software/product strategy/etc. leaks happening inside Apple. So you often end up with a rumor of "Apple plans to add hardware feature X", lacking the story of "OK, but why? How will we use it? What will it cost?"

Features that happen almost entirely in software are typically not rumored; see e.g. Center Stage. Nobody had "Apple will add machine learning-enhanced automatic pan+zoom to FaceTime on iPad Pro" on their bingo card.
