My comment about asdf mostly comes from my experiences back in 2005 when I repeatedly heard that Common Lisp had NO problems and that asdf was so superior to CPAN or rubygems that there was no need to implement a new package system. In the same way, I often heard that we didn't have an issue with insufficient libraries, since UFFI (or was it CFFI?) has solved all of that. I wouldn't have been surprised if those same commentators would today declare that QuickLisp has solved everything.
However, those conversation that I had back in 2005 were not with you and I apologize for putting words in your mouth.
