      Lock-Free Reads and SERVER-53436 changed writes to appliedThrough that used to be with a Timestamp on lastApplied.

      These writes are protected with the RSTL in X mode to ensure there are no readers. But with lock free reads that does no longer prevent readers from starting.

      Doing this change was safe because without EMRC=false we don't need this document for recovery and a clean shutdown would be required for a downgrade.

      However we should be able to clean up this more when the code for RMRC=false is removed.
