lol what you’re describing as a ‘feature’ is actually insecure & vulnerable. There are strong security reasons why Apple mandates WKWebView and bans SFSafari.
SFSafariViewController is not banned. It's recommended by Apple for some use cases. It says,
> If your app lets users view websites from anywhere on the Internet, use the SFSafariViewController class. If your app customizes, interacts with, or controls the display of web content, use the WKWebView class.
