Honestly, apart from the camera, those features don't sound like "must have" features that makes one rush out immediately to upgrade. I am beginning to suspect that iPhone upgrade cycles are increasingly being driven by ease of access to financing options and trade-in offers. It would explain why Apple is being more aggressive in these areas. They sound boring to Macrumours users, but remain crucial in getting more phones into the hands of users while allowing Apple to still maintain their margins.
This is a departure from back when upgrading was viewed largely as a function of feature sets (ie: existing iPhone users upgrading when a new device has features that appeal to them). And I think that moving forward, reviews of how each new generation of iPhones has only iterative / marginal improvements over the previous generation grows increasingly irrelevant, because that's not what drive device upgrades anymore.
In this context, the recent news of iPhone 14s being more readily repairable makes sense. It's also a reminder of why iPhone sales alone don't paint an accurate picture of how well the Apple ecosystem is doing, because it doesn't capture the sales of 2nd hand (and maybe even third hand) iPhones. It also throws the conspiracy theories of forced obsolescence out of the window, especially when you consider that iPhones easily get 5-6 years of software support.
Moving forward, the iPhone install base will only continue to grow, and the ecosystem ever more sticky, and so to what this means for Android, well, that will be fun to watch.
