An over-crowded open-office is even more productivity destroying than an open-office of a "normal" density. Plus, like already said, you can increase density (at least if the target is not overdensity) in other configurations... Maybe it's more difficult to over-crowd if you don't have an open-office, but that's a feature, not a bug.
