It works if frame-or-window is an internal window, I changed 'live' with
'valid'

I agree with Eli it should autoloaded, but every windmove function seems
to be focused on something to do with directional windows, these
functions would be a bit out of place.

How does a new autoloaded window-util.el sound? if you think its a good
idea I can also spend some time making an ace-window like window jump
function to make window-util a bit more complete. Which instead of
acewin puts a letter or number in the window's modeline instead, and if
you enter that letter/number you go to that window (the idea is to save
letter in a window-parameter, and use that in modeline)
