It's amazing that the function returns exactly what we need
even though its return value is not yet used anywhere.
So I copied the same design to another similar function
display-buffer-override-next-command to return exitfun as well.

You are welcome to sign papers, so the next time you could offer a patch.
Now I pushed the implementation based on your suggestion, thanks for it!

(The implementation also includes a lot of small details like correctly
handling the messages, etc.)

If you are running on 27.2, you could still take the second part
of repeat.el from Emacs 28.
