This is one of a series of innovations happening recently to improve Haskell's package ecosystem (which was not tooo bad to begin with). If "cabal hell" or anything like that has even ruined your attempt at Haskell: this is the time to try again.
The language and ecosystem are really mature now. But the main reason to go Haskell is simple and still the same: less bugs.
