I think rotation makes sense in vanilla icomplete, but not in
icomplete-vertical-mode.  So for the latter, I think I will just take
the cue from Vertico and use an index (or equivalent).  Since it's in
GNU ELPA, maybe even borrow some code :-)

I have a vague recollection that Someone Somewhere (tm) in one of my
extensions over at GitHub tried it out and found it could mostly work
with some tweaks.  Will search for it.
