+Min. Unfortunately, I don’t think the framework is enhanced for all the different kinds of resources, but it should be the way to go. IMHO Serialization through states was/is just a hacky way of getting around the situation and should be discontinued. Ideally, state of a resource should reflect only its lifecycle not the operations such as snapshotting, migrating etc.
