It's technically more an epilogue to both Enterprise and the 4 Berman Trek series. The conflict in it is an extremely shallow vehicle, or even just a backdrop to show the founding of the Federation and for the producers to say goodbye after a 20 year run. For all intents and purposes, the two episodes before it conclude the narrative of season 1-4. So I don't really look at it as some kind of Injustice. It could have aired 5 years later exactly the same and nothing would change.
