   The option of changing the filename is not applicable to the use case in mind. Suppose a PutFile is writing an updated file used by a Controller Service. The Controller Service will reload the file when a change is detected, but it requires the filename to remain the same. Therefore, changing the filename upon PutFile failure and trying again is not possible in this scenario.
   
   Also, in the above use case, it is desirable to save (archive) the current file before replacing it. The archived file can be used as a fallback if the new file is corrupt or otherwise unusable. The archive also can provide a historical record of when a certain configuration changed.
   
   I'm not sure I follow the "error prone and too limiting". The rules as laid out seem pretty straight-forward. Can you further explain the concern or historical errors that occurred? Thanks.
