Of course.

I don't remember, but given that I do have a `.get-mru-window' function
of my own, as well as the fact that e.g. evil-mode's `evil-window-mru'
definition doesn't use `get-mru-window' either, makes me think that it
either wasn't available at the time or doesn't do what I or evil authors
wanted.
