I think it would be a good idea to some feedback and more widespread use first.
I've started the process with https://dev.clojure.org/jira/browse/CLJ-2234. The other semantic changes need more review. The main performance change to clojure.lang.MultiFn is to replace persistent data structures by standard Java ones, eg, clojure.lang.PersistentHashMap by java.util.HashMap (acting as though java.util.HashMap was immutable).This suggests that are opportunities for improving the performance of Clojure collections, which would benefit more than just multimethods. However, that's outside my scope for now. In the meantime, this library will be available and it shouldn't be too hard to migrate from the Clojure implementation (and back again later if that turns out to be possible).
