We do use other ecosystems, yes. I haven't really found the tooling for Haskell to be particularly obstructive compared to other languages. I've run into plenty of mysteries in the typescript, python, ObjC/Swift, etc. ecosystems that have been just as irritating (sometimes much more irritating), and generally find that while HLS can be a bit janky, GHC is very good and I spend less time scratching my head looking at a piece of code that should work but does something wild than in other languages.
