To be fair, most of the games revolve a lot around the impact the Dwemer left on Tamriel. The events of Morrowind would simply not have happened had the Dwemer not messed with the Heart of Lorkhan, and without the Numidium, the Empire would probably not exist. How many of Skyrim's quest plots need a Dwemer invention or ruin to get rolling?...Really, you couldn't ask for much more without the Dwemer themselves showing up in force.

That said, I think that if they pulled it off well, the "return" of the Dwemer--or the threat of their return--could make for a very interesting story.
