I Haskelled quite a lot from 2014 to 2017 on a futile side project, and developed/extracted and maintained a few libraries on Hackage and a couple that were included on Stackage. In my experience most of the breakage comes from dependencies, not the language. The biggest shift in my time was the Functor-Monad-Applicative Proposal and I don't think that broke anything for me. Technically it was not even a change in the language but in core type-classes distributed with GHC and used in every Haskell program. As far as I know, Haskell 98 still compiles most of the same programs it did 25 years ago. Some extensions that are commonly used have introduced breaking changes I believe, but I don't remember the details. But I gave up maintaining my projects because 1. I wasn't using them (because I moved away from Haskell, for mostly the reasons in the OP which I feel like I could have written myself almost) and 2. my dependencies kept breaking them.
