Prior to ~~SERVER-94800~~ which got enabled in 8.2 (~~SERVER-106728~~), the ReshardingRecipientService used to fast count for the documents in the oplog buffer collection to restore the 'oplogEntriesFetched' in-memory metric which is then used for calculating the remaining time estimate. The concurrency_sharded_initial_sync suite performs file-based initial sync which is known to lead to incorrect fast counts. Please see BF-39456.
