My observation with the Scala and Haskell ecosystems has been very similar. One primary source of churn is changing interfaces. And very advanced static type systems offer a large design space how to model interfaces. Which leads to lots of incremental improvements. But lots of interface changes together with deep dependency trees lead to exponential explosion of changes.
Rich Hickey has been discussing this very early, but almost nobody got it when he said it, myself included. Striving for obviously simple interfaces, that avoid nominal static types like the plague, is the way to avoid this often pointless waves of changes through language ecosystem, just because someone designed a better option monad or whatever.
