Comment(by guest):

 GHC warns about non-dangerous things. What's dangerous about redundant
 imports, or unused variable names? The hierarchical modules are hardly
 unstable new innovations; Data.List or Control.Monad aren't moving around.
 And further, aren't the new module names an *improvement*? I mean, that's
 why they were created in the first place, right, because the Haskell '98
 choices weren't so good. More than a decade later, it's time for people to
 use the module names people expect. If people really want to use ancient
 module names, then that's fine; this is just a warning and not an error.
