I would say to the contrary it would come up all the time if the right idioms were in place.

For example, when it comes to concurrent access to a map the Clojure community generally forces a dichotomy, either stick a standard Clojure map in an atom and get fully atomic semantics at the expense of serial write performance or use a Java ConcurrentMap at the expense of inter-key atomicity (or do a more gnarly atom around a map itself containing atoms which gets quite messy quite fast).

Such a stark tradeoff doesn't need to exist! In theory STM gives you exactly the granularity you need where you can access the keys that you need atomicity for and only those keys together while allowing concurrent writes to anything else that doesn't touch those keys (this is exactly how e.g. the stm-containers library for Haskell works that's linked elsewhere).
