minibuffer-ins-buffer-file-name in emacs23 yet?

[jidanni]

Is this functionality somewhere in emacs23 yet?:
>C-c C-f runs the command minibuffer-ins-buffer-file-name, which is an
>interactive compiled Lisp function in `mini-ibfn.el'.

So I don't need to carry around the private file mini-ibfn.el anymore?
Should I submit a bug to get it added if not?
