What is the new behavior?

While mutating is a valuable concept, having it treated as a distinct state alongside Adding and Deleting causes confusion. Adding and deleting are also mutable operation states, though the concept of an enum indicates that they are distinct. Aligning DaffState more closely with CRUD distinctions presents a more familiar and predicatable operation state model.

The concept of mutating will still be supported at a state layer as an OR of adding, updating, or deleting.

The only possible concern here is the inability to determine the exact role of an operation as it pertains to the CRUD paradigm and therefore being unable to make a good choice as to the DaffState to represent the operation. Mutating and Mutated are, for this reason, left in a deprecated state (rather than removed) to further evaluate the use cases.
