      If the shardingFullDDLSupportTimestampedVersion feature flags is enable the chunks in config.chunks are indexed by and contains the UUID of the collection. While the legacy createCollection code takes this into account, the new createCollection coordinator doesn't check for this feature flags and unconditionally attach the UUID fields to the initial chunks. 

      We didn't spot this bug till now because we either test with all the feature flags enable or with all of them disable.
