What web developers think:
- User: "This site is broken. Fuck Safari, I want Chrome on my iPhone!"
What users actually think:
- User: "This site is broken. Fuck it, I'll go to another site."
Safari isn't THAT BAD that sites can't work on it. It's mostly minor differences, and lack of some "nice-to-haves" that are not crucial to UX (or in fact, their lack improves UX).
No one cares about your site that much to go to another browser just to browse it ON A PHONE. This is why I said, outside the web dev echo chamber, no one cares.
I've been around for IE6, and comparing Safari with IE6 is honestly absolutely ignorant and laughable. But I did also make my sites work fine with IE6 back in the time. That's our job.
Safari will move at its own pace. The only thing I care about it, is that it's secure, power efficient, fast and user friendly. I speak also as an iPhone user, because users matter more than developers and their endless whining about features.
