This would be bad. Of course there must be some core libraries that have to
be shipped with the compiler. Cabal and anything that cabal needs to run is
definitely a must-have. What I am arguing for (and Bulat, if I understand
him correctly) is that it's ok if building the _compiler itself_ (or
profiler or whatever else (apart from some exceptions like cabal) is
shipped with the compiler) needs libraries from outside the core library
set.
