PS1, Line 285:             DeleteObjectsRequest.Builder deleteReqBuilder =
             :                     
DeleteObjectsRequest.builder().bucket(bucket).delete(delete);
             :             if (config.getChecksumBehavior() == 
S3ChecksumBehavior.WHEN_REQUIRED) {
             :                 // DeleteObjects needs a request-body integrity 
header; when_required suppresses the SDK's flexible
             :                 // checksum and it no longer adds Content-MD5, 
so request an explicit checksum for S3-compatible stores
             :                 // 
https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObjects.html
             :                 
deleteReqBuilder.checksumAlgorithm(ChecksumAlgorithm.CRC32_C);
             :             }
             :             DeleteObjectsResponse deleteObjectsResponse = 
s3Client.deleteObjects(deleteReqBuilder.build());
I would prefer this behavior be optionally controlled by a `CloudProperties` 
flag, but we can do that in the future in a backwards-compatible way (e.g. a 
`CLOUD_STORAGE_S3_DELETE_OBJECTS_INCLUDE_CRC32_CHECKSUM` can default to 
checksum `behavior == WHEN_REQUIRED` or similar)
