That it's a command-line application also means it's "start up and throw away" which is easier to get working for most users than daemon based stuff. Typically once it's configured you don't touch it again. This allows people to build on each other's work which can lead to higher levels of abstraction and more human-oriented tooling.
The alternative is everybody having to write Haskell parsers and analysis tools over and over again before getting to the parts that actually make their editor/IDE different. The Clojure community has a similar ethos of tool sharing and reuse.
End users do not generally invoke these command line tools themselves, their editors/IDEs integrate them and offer the native trimmings the users would expect.
Why are you being so hostile? You're not making me want to share anything I know. I'm talking about the kinds of ecosystems that let people like you (that work on live-editing environments) focus on the parts that matter to you and you're behaving like a prick.
