Maybe Delta Vega isn't a planet given it's proximity to Vulcan, just a moon that exists in the NuTimeline but didn't exist in the Prime Universe. So in the Prime Universe there's a Vulcan with no moon, and in the NuTimeline there's a moon with no Vulcan.
The "prime" Vulcan can't even decide if it's got moons, a sister planet with moons ("Yesteryear", the first two versions of TMP, all the old novels and manuals) or if it's got no moons or sister planet at all (TOS, TNG).
Saying Delta Vega is proof of a totally seperate timeline (which contradicts the movie, which says "back in time" and "new chain of incidents, beginning with the attack on the USS Kelvin") is hardly definitive.
On the contrary, it was settled with the release of the Director's Edition of TMP. Here is the link:

So hence "throwing" a planetary reference to something that is obviously not supposed to be there is utter BS.
