      We currently achieve causal consistency by forcing another refresh here:

      https://github.com/mongodb/mongo/blob/r4.4.0-rc12/src/mongo/s/catalog_cache.cpp#L324

      However, it is possible to improve this if we know the clusterTime when the refresh was requested and the some indication of how "fresh" the cache is in terms of clusterTime.
