I would not recommend spending time on the v1 model, unless you're a historian.
There is one edge case that I think still works better under cabal v1- commands: https://github.com/haskell/cabal/issues/6515 This is where you create a shared, read-only set of packages (e.g., in a computer lab image) so that students don't fill their $HOME with compiled packages. Other than that, the v2-commands are a major step forward. -- Jack
