> The question is thus: remap exit-minibuffer or not?

Good question.  I think if there is a default value (i.e. if
exit-minibuffer would return that non-nil default when the minibuffer
is empty), then I think it makes sense to use the new
icomplete-show-matches-on-no-input, but if not, indeed we probably
should return "" (otherwise we're making it impossible to return "").
