+        for a resource as of how it existed at that point in time. This is why we
+        request matching entities with at most the provided resource version, and
+        return only the one with the highest resource version. In the case of not
+        specifying a resource version (i.e. resource version zero), it is
+        interpreted as the latest version of the given entity, thus we instead
+        query the "entity" table (which holds only the latest version of
+        non-deleted entities) and we don't need to specify anything else. The
+        "entity" table has a unique constraint on (namespace, group, resource,
+        name), so we're guaranteed to have at most one matching row.
