Comment (by malcolm.wallace at cs.york.ac.uk):

 Another important use-case is if I have lots of libraries installed by
 Cabal, then at some later stage I realise that I want profiling versions
 of all of them.  If the original sources were still lying around in a
 canonical location, this would probably be pretty easy.  One thing I
 definitely don't want is for cabal-install to download and install
 ''different'' versions of those libraries, just because newer ones are
 available.
