-fwarn-unused-imports message

[S.D.Mechveliani]

Hello,

ghc-pre-4.07  -fwarn-unused-imports

says to my   ` import M () '

  .../M.hs:42:
  Warning: Module `M' is imported, but nothing from it is used
 

Should it add  "except, maybe, instances"  ?
Because removing this import may cause the error report about the 
lack of some instances.
