I'm a fan who a) likes the Maroons fine, b) would prefer they not and ,c) will be fairly apathetic I'd they do. In abstract, I object to fan service for fan service sake. Which is exactly how the list by FederationHistorian appeared. No story reasons just "wouldn't it be cool if...?"Seems I'm in the minority that a) love the maroons and b) would like to see a Kelvin take on them.
Why not? It's just window dressing at the end of the day. Fan service you might say. It's the story that's the really important thing.
But, if characters and story are there then that's 80 percent of the way.
