When featureFlagUseUnreplicatedTruncatesForDeletions is enabled, change collection entries are removed via unreplicated truncates. This means the change collection entries of different nodes in a replica set can be truncated at different rates. 

It's not safe to check change collection entries through dbHash in the typical manner. Instead, a check similar the pre-image check added as part of SERVER-75440 should be added to guarantee the change entries are consistent.
