Please, please, please, packages can come "as standard" (i.e. be a core package) without having all their modules be part of the base package.
As I've mentioned before, a reason to keep it in base in future is that it gives us the opportunity to rewrite programs that don't even import ByteString into more efficient versions, for example:
f . lines =<< readFile "foo"
to
f . map unpack . B.lines =<< B.readFile "foo"
(is B ByteString.Lazy here?) If we want to do that then we'd either need to put ByteString into base or split io out into its own package, yes (and incidentally, the latter I think would be fantastic; looking only at the cabal dependencies and (transitively, admittedly) extensions you would be able to see if a library was able to do IO).
