      We currently think this was only necessary for mmapv1 when updates could cause a collection scan to miss a document. If we could remove this step, it could significantly speed up initial sync in certain workloads and simplify initial sync.

      This would require the storage engine API to prohibit updates from causing collection scans to miss a document.
