I'm not sure they are, but I'm not an expert.  If they are, then of course 
your proposal would be okay.

The purpose of the discussion (AFAIU) is to introduce a change to make it 
possible for icomplete/ido/... to put a too long overlay at EOB (with say 
two or three more candidates than can be displayed in the mini-window), in 
such a way that the prompt will always be displayed, and the last part of 
the overlay will not.  What happens with your proposal when 
max-mini-window-height is 10, and the overlay needs 13 lines?  What 
happens when max-mini-window-height, the overlay needs 10 lines, and the 
prompt and user input so far need two lines?
