If we try to delete a non-existing blob storage.delete(nonExistingBlob) returns false.
If we try to delete a non-existing blob with a batch request:

BatchRequest batchRequest = BatchRequest.builder()
    .delete(nonExistingBlob)
    .build();
...
batchResponse.deletes().get(0).failed(); // This is true

The deletion of a non-existing-blob is considered a failure in BatchResponse.
Wouldn't it be better to make this two ways of deleting a blob exhibit the same behavior?
