> {{findAndUpdate}} returns the previous state of the document (when applicable). However, this information is not always needed by the caller and may be expensive to obtain.
> Thus split the API into two different methods, so that DocumentStore implementations can optimized the void variant.
> Proposal: {{void updateConditional}} and {{T findAndUpdateConditional}}.
