    Description

      Rollback via recover to a stable timestamp should save indexes from the ident reaper, if the reaper has not already run on that index, meaning dropIndexes occurred far enough in the past that PIT reads can no longer access the index.

      I am not sure what kind of timestamping or history cleanup occurs around rollback via refetch, whether indexes can be saved from the reaper.

      This must be done after SERVER-38548 introduces two-phase index drop.
