I've used it in the past for document storage updates when documents can be rather large. It is always a toss up, design wise, to patch a single object or to save a log of actions (applied either on the server or the client). The former uses less space and has faster "time to final object state" on the client whereas the latter allows for time travelling and can make debugging much easier.
