- minimum, every reference contains a StorageUri. If the reference came from a
- bucket listing (as opposed to a manually instantiated ref that might populate

- depending on whether it was a reference to an object or was just a prefix of a
- path (i.e., bucket subdirectory). The latter happens when the bucket was
- listed using delimiter='/'.

- Note that Keys are shallow-populated, based on the contents extracted from
- parsing a bucket listing. This includes name, length, and other fields
- (basically, the info listed by gsutil ls -l), but does not include information
- like ACL and location (which require separate server requests, which is why
- there's a separate gsutil ls -L option to get this more detailed info).
