I have put forward an alternative plan



--------



Currently (icomplete-mode 1) is necessary.   And (icomplete-vertical-mode 1) is relatively new.
Emacs could ditch (icomplete-vertical-mode 1).

Instead, have a variable one can set (such functionality is already being done for completion-style).

Users can just put 

(icomplete-mode 1)
(setq icomplete-vertical 1)



--------



To disable, one could use 
(setq icomplete-vertical 0)    

Moreover one can use negative numbers
(setq icomplete-vertical -1) 



--------

To disable icomplete totally, use
(icomplete-mode 0)



--------

In summary there shall be no 



(icomplete-vertical-mode 1) 



or 



(icomplete-vertical-mode 0) 

--------

This will require adding separate `fido-vertical-mode'.
