Except you can't. Every browser on iOS uses Safari's rendering engine. Chrome/Firefox on iOS are effectively reskinned Safari. This is an apple requirement. The rendering engine being the important part here when talking about standards and such.
A rendering engine is not a browser. Are all the Chrome engine variants really just Chrome in a skin? I don’t think so they all have unique properties that set them apart. As do Orion, Firefox, brave, etc on iOS
I wouldn't consider other chromium browsers reskinned because they're using the chromium engine as a dependency, by choice. They can customize it as much or as little as they want (and I'd imagine they do to various extents).
Browsers on iOS can't - they are required (legally, not technologically) to use (a worse version of) Safari's engine. Chrome for iOS is not the browser that the chrome team wants to distribute, it's a browser Apple made that has been customized to the extent that Apple allows it to be customized. What is that if not reskinned?
Every time this discussion happens a non-trivial number of people reveal they’ve fallen into this trap of believing other browsers are allowed on iOS. Feels like a consumer protection issue, at some level.
I tried Orion (m1 MBP) recently. From about 3wks ago til a few days ago. I liked the UI. But there were a lot of pages that didn’t work correctly. I persevered for a while. But gave up a few days ago and went back to Brave.
