> Components: fs/s3

> {{MetadataStoreTestBase.testListChildren}} would be improved with the ability
> to query the features offered by the store, and the outcome of {{put()}}, so
> probe the correctness of the authoritative mode
> # Add predicate to MetadataStore interface
> {{supportsAuthoritativeDirectories()}} or similar
> # If #1 is true, assert that directory is fully cached after changes
> # Add "isNew" flag to MetadataStore.put(DirListingMetadata); use to verify
> when changes are made
