Habitat uses some simple data structures that are basically CRDTs. We used them because they made the user experience better (not needing infrastructure other than the gossip itself). One thing I learned early on that journey was that the more specific your use case, the easier a fully distributed model is. As soon as you need generic primitives a-la etcd or zookeeper, everything gets orders of magnitude harder.
