You can grab all the bindings of fido-mode in one swoop like this, I
think you can put this:

  (use-local-map (make-composed-keymap icomplete-fido-mode-map
                                       (current-local-map)))

Somewhere in your icomplete-minibuffer-setup-hook.

If it helps, here is a list of the variables that fido-mode sets for
you.

    (setq-local icomplete-tidy-shadowed-file-names t
                icomplete-show-matches-on-no-input t
                icomplete-hide-common-prefix nil
                completion-styles '(flex)
                completion-flex-nospace nil
                completion-category-defaults nil)

It seems to leave `completion-category-overrides' alone, so you should
be able to use to have the last word.  If completion-category-overrides
were to allow `t` entries, or some kind of catch-all, then it would be
the "ultimate" last word.

This would make sense to me, and fido-mode would commit to not touching
that variable explicitly.  I think this would make an(other) elegant
solution for this question, don't you think?
