However, as far as moving packages goes, it would probably be fine to wait until someone explicitly asks for something that was in web to be made available in core.
I would like to ask for haskell-lens. It is not really web
based, don't have much dependencies ...
I had been surprised to see it sit on haskell-web so it would be awesome to see it on haskell-core.
Cabal-dev would be nice (it was not in haskell-web).
Another nice addition would be haskell-pipes when the whole suit is ready.
