Comment(by simonmar):
Ian's right. We use the library proposal process for making changes to
the base package, and separately there can be a Haskell' proposal for
changing the Report and the official standard libraries (the `haskell98`
and `haskell2010` packages).
However, if this proposal is implemented, it would cause a problem for
GHC's Haskell 98 support, which currently shares the `Prelude` with the
base package. (Haskell 2010 is unaffected, because it has its own
`Prelude` in the `haskell2010` package). Thus, we would need to add a
Haskell 98 `Prelude` to the `haskell98` package, which would then become
incompatible with `base`, in the same way that `haskell2010` is.
