I feel like there were a few cases where this has happened, and Steam actually still had the game stored for people who had purchased to download, it was just that no one else could buy the game. Not sure if those cases were the publisher not wanting to generate bad will among its customers, or if Steam's contract with the publisher states outright that even when the game is pulled from the platform it must remain available for people who have already purchased it. Either way, it would certainly be the case that any future patches wouldn't be pushed to Steam.
