Some want a particular ride introduced because it will be uber in the MA; B-29, King Tiger etc. Of course all three sides will get the ride, so I'm not sure why. Other's want something because they have a historical attachment to it; i.e. Finns and the Brewster.
The He-111 would be a hangar queen in the MA, its usefulness would be for special events. It, or for that matter a Wellington, SM79, Betty, IL-4 etc, could sub for each other much better than the too-fast Boston or Ju88 currently can. Our early war fighters often have trouble keeping up with these two bombers, let alone shooting them down.
