I'm pretty sure it's because the events wouldn't make sense. At the time this villain appeared in the comics Starswirl was still teaching a young Celestia and Luna which means Sombra probably wasn't even born at that time. Considering how he fought Adult Celestia and Luna instead of when they were younger. Also he was already reformed in the comics as well so no way he's going to return as a villain. Not to mention the show even said they won't use him again.
