Yes but my point stands. If AWS added S3 data integrity to the SLA then it’s now made that commitment contractually. If you add checksum data the checksums would (logically) be required and also be in scope of the SLA. If there was a mismatch between them and the file functioned it would be impossible to sanely adjudicate who is responsible for the discrepancy, or what the nature of that discrepancy might be if no other copies of the file exist.

AWS probably doesn’t want those risks and ambiguities.
