Comment(by luite):

 I also think that the main problem is the time between GHC and compatible
 cabal-install releases is the main problem. Having an older cabal-install
 usually works if you stick to command line tools, but once you need to
 read data files produced by cabal-install, you quickly run into trouble if
 your program has been compiled with a different version of the Cabal
 library. The obvious solution would be to have the user recompile their
 cabal-install with the current GHC compiler, but that's been impossible
 for quite some time now

 (real-world use case: getting information about configured package
 dependencies for a cabal project, where the project has been configured
 with cabal-dev)
