In my experience at least, the time spent compiling value-level things is dwarfed by type-level computation and template haskell (e.g. creating lenses), which I wouldn't expect this would help. (My experience is backed up by a recent study on compile times of Haskell 98 code from old ghc versions to new -- for H98, compile times have stayed stable). If someone wants to work on this, though, I definitely wouldn't want to discourage them! It would still be helpful. Tom

Random thought about compile times: could separate compilation be made even more fine-grained by taking it to the level of individual top-level identifiers, rather than modules? This would probably help slow recompiles a lot.
