Not to discourage anyone, but the Haskell market is too small for anyone to
spend their time creating a Haskell IDE, unless it's a desire of them and
irrespective of the number of users.

The existence of a dedicated IDE is not a blocker for Haskell adoption, so
it won't have sizeable impact on the number of users.

Easy connection with HLS across different Cabal versions and interfaces
(v1, v2, etc.) would go a long way. That would help everyone, including
newcomers.

I'd love to be able to apt-get install vim-haskell-language-server and have
HLS enabled by default and working well with all my projects.

Cheers,

Ivan
