And give up on the screen size. The number of people who want a phone to fit in their hands and pockets is effectively zero compared to people who want huge screens to scale up content size or watch videos on their commute.
Not only that, but as an SE owner I can attest that many apps and web pages have more or less broken UIs on its screen. And I can't blame creators for not wanting to spend effort on a form factor with small and diminishing user share.
I'm the opposite type of (amateur) developer - I designed an app with an SE as my testing device. I was months into the development process before I said, "hey maybe I should look at the app on an XR." But it was pretty simple to scale the design up. I mostly just adjusted some left/right margins for the larger devices.
And frankly this is part of Apple's premium positioning. If your primary concern is comfort of the form factor, then you're not willing to sacrifice your comfort to signal that you're using Apple's [attainable-]luxury product, and if you're not willing to sacrifice for luxury you're probably not likely to pay for it in the first place. For now, they're happy to let those people go to the Android world. We'll see if that persists into this economic recession, or if they start to move more aggressively downmarket to boost their numbers. But it's a very valid strategy.
