tfishell: Galaxy is supposed to supercede the Downloader, and I think you can use Galaxy basically as you would the Downloader anyway. I suppose it's "optional" in that you could download through the browser instead of Galaxy.
Shendue: Not really, because you can't just download games with Galaxy and start them without using Galaxy afterwards. Once you download them with Galaxy, they will run Galaxy automatically whenever you launch the game.
You can use it offline, but it will run none the less. I do not want a client running in the background, period.
