claim is that very many things are not needed, but they are. they are just provided by the layer beneath (S3). so isn't correctness highly dependent on s3 correctness? was s3 built for that, vs just plain durability? for example, would it be just as reliable with minio? i would prefer a thing that was more self-contained, not dependent on a black box service layer underneath. much apologies if i just have a poor understanding.
