Well, might as well drop then entire stuff after the domain.com/{dump all this out} (the file path) since non-techy people don't really care about it. All they care is about clicking links and navigating...
Maybe the address bar UI will next hide query string parameters because they are an implementation detail? So Google News would be displayed as "news.google.com" instead of "news.google.com/?hl=en-US&gl=US&ceid=US:en".
There thankfully is a setting to show the full url, but yeah, Safari on macOS does that by default. The change occurred around Lion (give or take a major version) if memory serves me well.
From the business point of view that would make perfect sense. The user wont be able to remember the url and even second guess it so that would need the "help" of google, cause everyone knows that "google is your friend".
TBH, so long as there always remains the option to show the full URL, I'd be totally fine with completely hiding it by default. Safari all but does that right now.
