    Description

      Some users have asked whether the we could record the inverse of what's in the oplog, in order to perform roll-backward operations (e.g., record the values that get overwritten on updates).

      Obviously, this sort of thing gets hard/impractical in the presence of collection/database dropping, but even if the undos only went back to an empty collection/db, it could be useful for some problems.
