Well, I'd like to split up the "get all the information we need" bit
from the individual commands. That would perhaps make it easier to
validate things like "does GHC_PACKAGE_PATH [or whatever] point at an
existing directory" in a consistent manner across all commands and thus
hopefully provide better feedback for broken setups/environments.

(I also tend to find it good "hygiene" to split things up this way, but
that's perhaps more a matter of taste.)

See e.g. the issue I pointed to:
https://github.com/haskell/cabal/issues/2381 (I don't think a full
solution is possible at this time due to the fact that the env variables
are only retrieved in the "exec" subcommand).
