Is there any obvious "extra" functionality from the alternate IF deck?

Any obvious "missing" functionality from it?

While there were special editions for NATO allies that add extra
switches/subchassis for SSB, I could imagine other special editions that
would have best been done with a whole new IF deck.

Packing more parts per cubic inch in there is undoubtedly possible :-).
