Those are breadcrumbs, not an address bar. Note the fact you cannot type or paste a path into it, as is a core feature in practically every file manager in every other OS. There is no apparent difference to breaking this convention, beyond impairing users' workflows. Finder also has the "Go to" dialogue, but again, it is a functionally inferior solution.
There is absolutely no good reason for these design choices other than to "be different for the sake of it" at the expense of good UX
Unlike address bars in other OS file managers:
- Finder Go To does not provide suggestions/completions (unless there is only one single match in the current folder, it'll complete the name of that)
- Finder Go To does not respect the current directory (it always uses `~/Library`) making relative navigation tedious
- It's an entirely separate action and UX flow for absolutely no good reason
In any other OS one can open the file manager, press Ctrl+L and start typing a path, pressing tab at any point to get contextual completion suggestions.
I'm not sure what you're using (⇧⌘G, right?) but mine does all of those things. It gives me multiple suggestions if there is more than one match, and it lets you enter a directory in your current path if you just type that folder's name.

Not completely: you can do two windows side-by-side, and resizing windows now makes them snap to each other and edges.
