They are persistent as long as you use the public API. Not all public methods on implementation classes are part of the public API. It would be nice if clojure.lang.* methods had it reflected in the docs, but we have what we have. I can't know for sure but assume that clojure.lang.* classes were not meant to be used directly or from Java, unless absolutely necessary. There is no absolute immutability on the JVM, .NET, in JavaScript. There is always a backdoor to mutability. But 99.9% of projects won't use it. If you think that this is scary, dig deeper and you will find plenty of libraries that use native dependencies. With those, you are basically one issue away from having your entire VM terminate.
