And it's amazing how rapidly they are able to invent a whole new programming language, compiler, toolchain, overhaul the OS APIs, add new OS features, and innovate Apple-only "native" technologies on Macs, iPhones, iPads, and even watches, while porting some features from open-source browsers into Safari is so darned "challenging". (I'll bet Apple could get some help from organizations with more resources like, say, Mozilla or Opera, if they just asked.)
I might suspect that they were intentionally impeding the progress of the Web, sabotaging all of us while putting on a great show, if it weren't for the fact that they allow other browsers, such as Chrome, on the iPhone. No, if they wanted to slow the progress of the Web platform, they would slow the development of their own browser as much as they dared and simultaneously cut off all detours around it except the one that goes through their own native apps.
But no, they aren't doing anything like that, because there's Chrome right there in the App Store. As long as it's not some sort of trick, some sort of imposter, there's no reason for suspicion....

I must say this fact makes reading your last sentence quite humorous.
Chrome does not run on the iPhone - instead it's a Safari UIWKView (until two weeks ago UIWebView) - the only "Chrome" there is the UI on top of it.
Apple does not actually allow running Chrome on iOS so Google worked around it by giving you a handicapped version of Safari with Chrome UI that lets you share tabs between the computer and the box.
edit: just saw someone else posted a similar comment - so upvoted his - not deleting this since it has some additional info.
You think they aren't capable of that? Isn't it the same thing they are doing now with not supporting Vulkan and sabotaging open graphics API by pushing their lock-in Metal instead?
Unfortunately it doesn't seem to be open source.
People use things when they have utility. They have utility when developers make something cool that uses them. Developers do this if there's a chance of mainstream adoption...
