the other branches of the franchise inevitably fall into dealing with war outright, be it war with the klingons, the dominion, the xindi or the borg. the kelvin timeline appears not be as tied up in this kind of conflict, or the filmmakers have at least avoided this recurring concept.
The other branches have weekly episodes and seasons to tell their story and build up to any interstellar wars. This branch only gets the chance every 4 years, if that.
