I suspect a lot of this has to do with the fact that it took the CL community over two decades to create QuickLisp. It boggles my mind why this wasn't created sooner--perhaps sharing libraries wasn't a high priority because the libraries tended to be spotty to begin with? So you may have had a chicken/egg problem.
