Those were the engagements I'm thinking of.
You may be the first person I've met who considers the moral implications of strategic bombers in a combat flight simulator. I certainly haven't, so in that regard I commend you. However, please consider the following:
Normandy will be simulating the V-1 offensive, a very deliberate terror bombardment campaign. If we want to be especially contentious, there will be players on the German side who are going to be flying in support of these operations. Maybe not as an assigned mission set, but it's not hard to imagine what kind of target the flight of B-25/26/recon planes you've been sent to intercept is trying to reach if you're over northwestern France.
Speaking of the V-1 offensive, there are a variety of Operation Crossbow targets inside the map boundary that received attention from USAAF and RAF strategic bombers on numerous occasions (not limited to the tactical fighter action we will probably see against the bombs in the air and on the ground), that also don't involve razing a city. I consider this operation (including the tactical strikes and air defense against it) more of a strategic campaign then I do tactical, but it's being simulated all the same. The usage of strategic bombers here shouldn't be contentious.
In regards to Caen, my research may be off, but I believe that was one of the few times a city was the target during one of the aforementioned operations. Indeed, it was razed by accident, the bombers were supposed to hit defenses outside the city, and the other bombing operations hit areas outside of towns (such as in Cobra or Goodwood)
Ultimately, my want for strategic bombers is not from any blood lust for collateral damage, its for historical accuracy. We're finally in a theater that regularly included both strategic bombers and tactical fighter bombers on the same operations, and saying its a "tactical air war simulator" as an excuse doesn't fly anymore.
