I really do hope that not too many people feel like the message is "keep out". In recent years the community has generally strived to be welcoming to beginners and share the excitment of learning Haskell, without the arrogance.
The aforementioned tooling improvements were only possible because a bunch of excellent people did exactly what you mention: tackle everyday productivity and pleasantness by improving IDE integration deep into the stack, all the way to the information the compiler makes available to the tooling.
If you want to get a fresh impression, ZuriHac [1] is happening (remotely) this weekend, and there is an online class for absolute beginners held by the excellent Julie Moronuki (of haskellbook.com fame).
Disclaimer: I'm very biased, because I'm a co-organizer, but I think it will be great fun!
