Right now ($!) operator can be imported either from Prelude or GHC.Base. The later is specific to GHC, so it makes sense to avoid it.
There are reasons to avoid Prelude too (e.g. because it pollutes name space, changes too often, etc.) We need a home module for all identifies from Prelude, so that one can import them without importing Prelude.
I don't understand. If you don't like to import it, you can import Prelude hiding (($!)) If you have disabled automatic import of Prelude, you can still import it selectively by: import Prelude (($!))
Data.Functor seems to be a good candidate for ($!) operator home module. It already exports ($) operator.
I think it would better fit in a module for 'seq' and friends. Unfortunately there is no such module yet.
