Comment (by danilo2):

 @simonpj: This is exactly what I'm doing right now. If I migh suggest one
 thing - maybe it would be better to just report to the user 2 separate
 errors at once? One about not met liberal coverage condition and the
 second analogous to the one known from ghc-7.6?
 This just saves a lot of time with adding and removing flags :)
