Are there GHC extensions we'd like to incorporate wholesale?

[Augustsson, Lennart]

I'd say there are extensions we should just adopt wholesale, but they are all of a very simple syntactic kind.
E.g., EmptyDataDecls, ExplicitNamespaces, KindSignatures(?), NamedFieldPuns (used be part of Haskell), RecordWildcards(?), TupleSections, TypeOperators.

I wonder if there are GHC extensions we'd like to promote as features in the next report, as a starting point for discussing new additions.

There are a few GHC features that have become part of the regular Haskell landscape, such that it's hard to imagine a modern Haskell without them. For example, MultiParamTypeClasses, OverloadedStrings, GADTs, TypeFamilies, etc.

How much "work" is typically involved in promoting a feature to be in the Report, and how do we determine when it's a bad idea?
