Does micromanagement, as a rule, equal realism? Of course, if you don't get a major shot of jollies from micromanagement you shouldn't be anywhere near WiTP. A it is.

With the new loading rates and such, in this case, yes. Otherwise, the Allied played would be limited to how much they can put onto assault shipping any given day since instead of having the Phillipines, Marinas and Okinawa, they will only have Okinawa. Even if Okinawa was abstracted as a level 10 port, the Allies (I assume) would be greatly limited as to how much shipping they could deal with on any given day.
This doesnt take into account the additional stacking penalties for planes and troops, which also would become a problem if only Okinawa were available.
