An argument can be made to change the definition, but that's what it is right now. A especially strong -1 from me to any effort to enforce Haskell 98 compatibility for Haskell Platform packages: that standard is 15 years old now, and has been superseded by Haskell 2010. At this point I think the argument for standards breaks down altogether because there's only one conformant Haskell 2010 implementation. It's not GHC's fault it doesn't have viable competitors: we shouldn't be making busy-work for package authors to make their code portable to other Haskell implementations that don't exist yet.
