Comment (by ezyang):

 The widespread use of GHC.Prim is primarily an accident induced by
 documentation: https://hackage.haskell.org/package/base-4.9.0.0/docs/GHC-
 Exts.html does not list all of the GHC.Prim functions; instead there's
 just a little "module GHC.Prim" deep inside. So if I'm looking up a
 function, the only Haddock page it is going to be on is GHC.Prim, and then
 of course I'm going to import GHC.Prim (if I am not paying close
 attention).

 So I guess what could be done is to change what the magical module is
 called, turn GHC.Prim into a real module, DON'T expose it, and this time
 correctly configure Haddock to inline the   description so that whatever
 your real module is called never gets exposed. A bit of faffing about but
 probably not fundamentally hard.
