Here's a serious downside of Haskell:

https://github.com/jwiegley/github/issues/25

Experienced and skilled developers (wiegley's open source work includes ledger and great contributions to emacs org-mode), and the task is to make the API client's base URL configurable. Should be trivial. And yet it descends into farcical stuff about whether they need to introduce a new github monad or to "abstract over a type class". It seems like the purity was really getting in their way. The issue was never solved. I may be cherry picking an example which serves to parody Haskell, but for me that example is really off putting.
