Haskell and Pandoc has too much dependency bloat. Just installing Pandoc on Arch requires like 200MB in dependencies, and over hundred haskell specific dependencies.

Well, firstly, I’d note that Haskell on Arch (including Pandoc) is broken, mostly due to the fact that Arch likes to dynamically link everything and Haskell doesn’t (see also https://www.reddit.com/r/haskell/comments/yuwcei). But yes, Haskell packages do often tend to have quite a lot of dependencies. To some extent this is because the base library is very much ‘batteries-excluded’, so dependencies are necessary for things like file management and byte strings and so on, but I do see quite a few dependencies which could be split up (e.g. ‘servant-server’, a big dependency used to create a webserver in exactly one module of pandoc).
