Eh, I pretty much considered the Abramverse an alternate one before Nero and Spock entered into it. All the Federation ships were bigger for example and their weaponry was different. And somehow I doubt Kirk growing up with daddy issues caused the Federation to vastly change ship designs, build the Enterprise in Iowa as opposed to San Fransisco Shipyard, different uniforms and another things.
Similar? Sure. But definitely different. Besides, it makes it easier for Abrams not having to keep up with any sort of continuity beyond his own work.
