What I'm suggesting is a bit narrower: I think stack should probably just ignore GHC boot packages altogether, aside from the necessary ones (I think just ghc-prim, ghc, base, and array, but you'd have to check the full GHC API to be sure). Never use them, and pretend they don't exist.
My personal understanding of Stackage is: It's a collection of packages with *exactly* one version of each package, and all those versions are guaranteed to work together. (<= Well, at least in the eyes of the resolver, not necessarily in a semantic way) So: As long as GHC exposes its "non-necessary" packages, whatever that means in detail, I doubt that there will be other versions of them on Stackage. That's what Hackage is for... Again: That's at least my understanding...
