Seems like the author is so used to the current design language, that they are vehemently opposed to any change.

I personally like that Apple attempts to make websites feel more like applications by making the browser disappear.

Websites have evolved to becoming essentially applications that can run on any platform. And with WASM this is only getting better. This is a great thing!

Do applications have a permanent bookmarks bar, a reload button, a URL bar? No. It's all built into the OS. When you want to open an application, you search in the Dock or in Spotlight. When an application freezes, you force quit and reopen it. I can imagine how Apple in the future integrates the Safari URL bar into Spotlight search. On iOS this is at least partly possible already. Websites become more and more applications.
