Description
While most DDLs just insert new document into config.placementHistory as part of their commit, moveChunk and renameCollection perform first a lookup into the same collection to retrieve the latest placement information and build a new document on top of it.
If such behaviour were removed, it could be possible to perform arbitrary trimming of the config.placementHistory log without the need to block any DDL.
