So to be compatible with the PATCH method json-patch must be atomic. Barring some type of transactional memory system won't this mean that you either must a) copy the target before applying the patch, or b) record a reverse patch to roll-back with? Seems there would only be benefit if the changes were very simple and the target very large.
