For instance the address bar on here is a canonical truth and is the linchpin of the experience. See how every time a browser touches it (e.g. Chrome truncating the address) is met with mobs of the angry. Many users -- including even "power" users -- seldom interact with the address bar. Nor is it verification of anything much. It simply isn't that important anymore.
Another comment mentions that the reload button is two clicks away, which is a fair point but that everyone who actually uses reload (generally developers -- zero web apps should ever require the user to hit reload) use a keyboard shortcut.
Eh.
"Certain UI changes in macOS, Windows, etc. are so obviously bad (and are eventually changed)"
True. At the same time, every UI change of anything ever has yielded a firestorm of criticism and pushback. And more times than not the new design was better and people acclimate to it and eventually prefer it. I judge nothing on initial reception.
