Well, as 1.4 isnt final yet, I think were going to stick with 1.3 for
NZO, as its stable and well tested. About the change being required,
well... its not exactly required, but having to duplicate a 20+ line
long method just for a 1-line change, and having to watch for changes
on the original product seems completely awkward to me.

|       return self._data_wrapper_class

Even better! Thats exactly what I had in mind (but of course for
including in HEAD, not in 1.3-branch).
