I am clearly missing something here. Could you please outline why such a monolithic repo would be good? As you pointed out yourself, the conceptual problem that different libraries won't walk in lockstep remains and segmented builds continue to be desired. Sure, repo checkout is easier but as long as segmentation exists I fail to see the advantage.
