Not to Brits and Yanks it isn't.
According to whom? Anyone with a knowledge of the war as a whole knows the Ju-88 was the LWs workhorse and the iconic German bomber of the war performing many different roles, those who care to read a bit more know that the He-111 was obsolete and the only reason it was kept in production past 1941 was the persistent delay of the He-177.
Such a statement is tantamount to calling the Wellington as the iconic plane of RAF Bomber Command... nevermind those silly Lancs!
In addition the 1941 Ju88A-4 has consistently demonstrated that Hurricane and Spitfire Mk Is are incapable of significantly hindering it.
Which has to do with the way bomber speeds are depicted in game, not with an specific plane in game, the A4 was little faster and some sources even say slower than the A1s and A5s of the early BoB.
Being faster and tougher than the C-47 it would make base captures easier, which HTC may not want.
1. There is not much of a speed difference on the deck where they would operate.
2. True, so? The Germans still used them as such.
3. Speculation.
One can ask that about a great many things, and conversely if the Ju188 had been added instead one could ask why the Ju188 is in the game when the He111 is not. And that is just limiting it to asking about German aircraft. Have you checked out the Russian bomber set?
I rather have the Do-217 or He-177 than the Ju-188 since we already have the 88. If any of the others is added the answer is simple, there was already an early war bomber in game, and no middle or late bombers.
Re. Russian bombers that is exactly my point, instead of having HT spend time and resources in designing a completely new German aircraft to fill a mission, it would be better to just make a quick version of an existing aircraft to fill that mission so HT can use its time and resources to make... Russian bombers or Ohka bombs or whatever they wish.
