Wow.  In a dired buffer in Carbon Emacs, I just executed
the following:

        (setq buffer-file-name ".")

And it did exactly the right expected useful thing: a badge was created that
represented the current directory, and I could command-click on the title bar
to see the filepath to the directory and select parent directories.

The question is, will this break anything else?  Can we make this a global
change, or at least a change on carbon emacs?

I know that I could personally add a hook that does this.  I'm just thinking
out loud for everyone.
