I agree. Whatever "unrecorded" history may or may not have occurred prior to the wish, Once Emma and Regina appeared there, the events that occur there are history relative to that realm.

Which means that the Wish Realm has as part of it's history the event of Regina killing Snow and David. That one is going to haunt Regina the rest of her life, particularly after she returns to Storybrooke and explaind to David and Snow how she managed to kill them in an alternate realm. That should be a really fun conversation.
