How would Mediterranean combat shape later carriers?

How might this war change the carriers designed afterward?

Mediterranean damage experience could push Japan and the United States toward British-style armoured flight decks.

Mediterranean attacks could give Allied designers direct comparisons between armoured and unarmoured carriers. In the proposed example, Sōryū or Enterprise suffers damage that keeps the ship out of action for a long period, while Illustrious returns sooner. Sōryū might even be sunk under comparable attack. Such an experience could increase interest in the Illustrious class's armoured flight deck when the next carriers were designed.
