REVISION SUMMARY
  This is a small duplication, and the last bit we need to get rid of the mixin.
  
  Honestly, I am not fan of that class attribute and it mostly exist to accomodate
  The simple-storage whose usage of flag processors is dumbious and that is
  currently dead code anyway. However I don't want to be pulled into futher
  unrelated cleaning so it is a small price to pay.
