Why are people stating this ? You can not do basic things like zooming the page for a preset factor in Safari.
Blind people for example don't care about zoom factors, but they care very much about the fact that they can completely control and use their iPhone using text-to-speech and certain gestures.
There was an issue with the graphics, and it initially booted into an assistive mode for first-time setup, and I wondered how a visually-impaired person would use the touchbar.
