I don’t think the plan is to have different implementations of stuff in base at the same time. If different compilers (fay) replace the base-implementing packages, then there is another implementation, but that would never interfere with a definition on GHC. Or what scenario do you have in mind?
I think his wish was to ensure that e.g. 'map' has the same type in GHC, fay, JHC and others, although it might be implemented differently (with foldr/build, or stream-fusion, or whatever).
