Since when did I say that I will give you security only? And I intentionally didn't cover specific security problems. I was obviously talking about "all aspects" and I pretty much touched a lot of the different parts of the browser.That was impressive...said no security expert. Only one of your suggestions has any application to real user security, and even then only barely. Good showing.
But hey, you do you.
In case you didn't know, there have been many zero day security risks, bugs and other security issues some of which remained unfixed for MANY years. From data theft, browser history, and even camera/mic exploits. But all browsers have been full of holes, not just Safari.
