Of curator? No. We're actually moving off curator/zk in favor of another
service discovery technology. I'm probably going to use the
[JsonInstanceSerializer
patch](https://github.com/apache/curator/blob/3ca02ea7f076d40333d664dd609962d0fe2e4c5f/curator-x-discovery/src/main/java/org/apache/curator/x/discovery/details/JsonInstanceSerializer.java)
in our upgraded clients. ---
