Storage drivers may be able to take advantage of the hint to start their walk more efficiently. For S3: The API takes a start-after parameter. Registries with many repositories can drastically reduce calls to s3 by telling s3 to only list results lexographically after the last parameter. For the fallback: We can start deeper in the tree and avoid statting the files and directories before the hint in a walk. For a filesystem this improves performance a little, but many of the API based drivers are currently treated like a filesystem, so this drastically improves the performance of GCP and Azure blob.
