In particular, this makes it impossible to implement a more efficient implementation of counting query results, as that requires the values from the skipped_results and more_results fields.

See https://groups.google.com/forum/#!topic/gcd-discuss/wH8lVOA-a8Y for an in-depth discussion of what's needed from query results to implement that.

Generally, skipped_results, more_results and snapshot_version should be available in QueryResults
