That depends on the chip manufacturer, in this case it’s Qualcomm. But they at least release all the source code, unlike MediaTek.

Personally I don’t really care about the stock camera app. I just want access to all camera features through the Camera2 API. Then I can install any app of my choice. This is currently limited (only the main sensor is accessible and it tops at 12MP), but FP is supposedly working on this. (https://forum.fairphone.com/t/fp4-gcam-port/79450/75?u=razem)
60 Hz display isn’t a dealbreaker to me, but yeah, it would be fine to have options. Similarly with OLED. In the end, the phone is modular so it should be somewhat possible.
Yeah, I would also prefer a slightly smaller screen. But I’m not sure it would sell that well. Many people simply prefer larger screens.
