I think it's more than avoiding feature creep.
I think the most interesting parts are
« It is more important for the implementation to be simple than the interface. » and « completeness must be sacrificed whenever implementation simplicity is jeopardized ».
I think of this every time I'm annoyed that I can't add an empty directory to a git repository.
Or in other words, try to avoid Feature Creep[0] or Overengineering[1]
