It's super easy to turn off in Safari Preferences though. Certainly easier than installing another browser.
This is the main problem with options over good defaults. An option requires enough understanding of the domain to realise that there might be other choices. It also requires enough knowledge to make that choice, especially for something that affects security (knowing if you're on a malicious website) but looks like a simple visual change (simplified URLs).
Usually it'll follow a pattern like:
"Hey friend, my browser is a bit rubbish, I can't see the page I'm on."
Friend uses Chrome and demonstrates how it doesn't do that.
"My friend's browser is better because the URL is clearer. I'll swap to that one."
Non-technical users will usually follow recommendations like that before they considering looking for an option to make the browser work the way they want it to. Configuration isn't something most users do unless it's either suggested by the application or there's a button literally in front of them.

and
then why would you actually need to see the full URL? Come to that, why would _anyone_ who isn't debugging a REST API need to see the full URL?
The address, however, still feels like it's behind a piece of glass--it animates to the left when I click it and highlights the whole address, not letting me find a spot to highlight until after this animation is done.
The behavior to center the URL in the location field when not in focus, but to reformat to the left when focused, is somewhat silly, though. (In someone's eyes, it's apparently a form sufficiently importantly impressive to go over function.)
Edit: That you can't grab and drag the icon associated to the URL (but rather the URL itself) is also inconsistent with the general UI. (In other words, Safari's location field is not a Mac UI element.)

The web is made of URLs and hiding them would be like taking the express train back to the AOL days. This "feature" would have brought negligible (if any) security, but would have made the web many times more difficult to use for both inexperienced and power users alike.
