And there's a problem: ghc-pkg uses Read, and that requires all the 
fields to be there. It would be a Bad Idea to force everyone to update 
every single package.conf file out there. Is there any special reason 
why it doesn't use the ParsePkgConf.y parser from compiler/main? (Simon: 
Am I allowed to make it do so?)

I don't see why I would want to add a Haskell-Framework to a 
package.conf file... I would definitely like to be able to 
drag&drop-install GHC-Packages (it could be done on all platforms, not 
only MacOS). It would require loading package.conf files from 
framework-style directories - I'll take a look at whether this could be 
done easily (and without disturbing the existing system) when I've got 
the more important things done.
