Comment(by igloo):

 Simon Marlow says:

 There is one problem that I know of with breaking up the compiler into
 separate packages: GHC will do too much recompilation when things change,
 which will make development somewhat painful.  I discovered this when
 making changes in hoopl: a small change in hoopl causes recompilation of
 nearly every module in GHC.  The reason is the way that GHC records
 dependencies across packages: rather than the fine-grained dependencies we
 get within a package, a dependency on a package module records only the
 ABI hash of the whole module.
