I think its great that someone is trying to make haskell not suck to use. Better still that its very ambitious as it means people will learn much if or when it doesn't meet its aspirations.
That's something I'm looking into doing myself. It would be great to help improve tools like cabal and the haskell-language-server.
I think that will go a long way towards making Haskell more beginner-friendly, and easier to use in production.
Personally, I use ClassyPrelude and only a handful of extensions.
