information on the various different use-cases first
One such use case is when employing [remote-signing for Iceberg
catalogs](https://github.com/apache/iceberg/blob/main/aws/src/main/resources/s3-signer-open-api.yaml).
When one loads a table from an Iceberg catalog with vended-credentials
access delegation, [the response is
sufficient](https://github.com/JanKaul/iceberg-rust/blob/main/iceberg-rust/src/object_store/parse.rs)
to construct an `ObjectStore` instance, and thus perform some read/write
actions on the table.
This isn't the case for remote-signing access delegation, as there's no way
to hook-up the `s3.signer.uri` and `s3.signer.endpoint` [that are
returned](https://github.com/lakekeeper/lakekeeper/blob/0ee94b265d4ad5c53e14dac09ccb3f4cdb270a77/crates/lakekeeper/src/service/storage/s3.rs#L542-L548)
so that the `S3Client` uses them to presign the request URL.
