/**
 * Manages a set of ids with optimistic add-and-rollback.
 *
 * Generalizes the alerts/unacknowledged-bulletins acknowledgement flow: an item
 * is hidden immediately by adding its id, the persistence call runs, and the id
 * is removed again if the call reports failure - so a failed write never leaves
 * a permanently hidden item.
 * @returns {UseOptimisticSetReturn} The set, membership test, and optimistic add.
