DropCollectionCoordinator is currently deleting the collection metadata and data without explicitly blocking any user write operation on the namespace. While this behaviour is aligned with the isolation guarantees offered by the DDL, it may lead to an inconsistent sequence of events in the primary shard oplog.

The addition of a RecoverableCriticalSection protecting the execution of the whole kDropCollection phase could be a way to solve this problem.
