We added some testing of what happens when an $out is executing with a stale cache, but we'd like to target the functionality introduced in SERVER-35954 which will also read the cache.
This will include the interesting test case of seeing what unique key is used if a mongos has a stale version of the cache which indicates that a collection is sharded but it actually is not, or if it is sharded but now with a different key.
