How is it breaking backwards compatibility?

- If people were somehow relying on sys.setdefaultencoding to be 
deleted, that's fine, it's still gone

- If people were somehow relying on sys not having an attribute called 
_setdefaultencoding, or were relying on stuffing an attribute into sys 
called _setdefaultencoding then... well... that seems pretty unlikely ;-)
