Another problem is that Safari is not compatible with the web. Like, I'm not going to prevent myself from using aspect ratios on images because some people made the bad decision of getting an inferior phone that locks them out of using good browsers. And many devs couldn't have known about it until the website was done and published to prod and iOS users started complaining about it because testing with Safari costs thousands of dollars in Apple hardware - and even if it was caught, it's still Apple's fault.
