The simple truth is that 99% of the time when browsing is spent on that "rectangular area".
Maybe the term "skin" is not adequate, but IMO the features added by Chrome and Firefox on iOS are not that significant for the browsing experience compared to the "rectangular area". Thanks to Apple, WKWebView based browsers are always going to be second class citizens.
Personally I never understood why you decided to move to iOS. I think you should have stick to your guns.
